I'm pretty sure goatpig will request for the full dbLog.txt and armorylog.txt later so you might have to post them sooner than later.
Those are usually large for a text file, so use https://pastebin.com/ to share the full logs.

You can upload them to any image hosting site like imgur.com then insert the direct link (with .png /.jpg / image extension) in your post using [img][/img]
but since you're newbie rank, those will be displayed as link temporarily (which is fine).

For the checksum, means that it could be shuffled since mistyping a word will produce a different error: "Unknown word <word>".
Unless the misspelled word produced a valid word from their legacy recovery phrase wordlist.

Is your Bitcoin core's blockchain pruned?
You can find the prune setting it in Bitcoin Core's: Settings->Options... | Prune block storage to <> GB.
If it's ticked (checked), Armory will not work.
Disabling it will require you to re-sync Bitcoin core from start and some extra disk space in the data directory (about 350GB+).

How about the parts of the log about the machine's specs, OS version and the set paths?
Those should be at the top of the log for the current session (check date/time).
Note: The log doesn't contain any info that'll compromise your security, but for your privacy you can exclude the username of the appdata directory.

About Bitcoin core, did you set a custom data directory or is it set to default?

I can't find the root of the issue in the log other than what's literally written.
Let's see what goatpig (Armory developer) and others can find with the current available info.

Yes, as long as the address is either SegWit or Legacy, you'll be able to export it to other wallets.
Here's a tutorial by HCP on how to export the key(s): https://bitcointalk.org/index.php?topic=4746784.msg43255691#msg43255691
Then you can import it to a wallet that has "import" feature.
But I'd suggest to use that as the last resort.

On the other hand, what version of Armory are you using?
You should be using the latest version 0.96.5.

Did you say "same address"? Means that you're not spending them and just using the same address since 2016?
Then seeing it when you restored the wallet.dat is a good sign, means that the private key of that address in in your wallet.
If so, you just have to finish the rescan, that will take a while but it wont cost you any internet bandwidth.

In comparison, it could take hours to a day or more in Bitcoin Core.

Your ftp link will not work like that.
You can paste it to https://pastebin.com/ instead, click "Create New Paste" below and link it to your post using [url][/url] tags.

As per usual, you should share armorylog.txt from Armory's data directory.

Without the logs, try to use the usual troubleshooting for "offline" issues: Armory might be looking at the wrong satoshi directory (bitcoin's data directory).
This happens when you set a non-default data directory in bitcoin core and didn't set Armory to find that directory.
You can set it in the "File->Settings->Blockchain and Database Paths", under "Bitcoin Home Dir".

If it's offline, it won't be able to scan for transaction history.

You have the option to export the private keys but since you already got the full blockchain, you might want to finish setting-up Armory instead of importing the keys to a less secure/private client.

If you read the previous posts, you'll see that the problem was: he misunderstood Electrum's receive tab, there's a "request amount" there and he probably mistook it as "Buy Bitcoin".
Never replied after his third so I think he figured it out because of Charles-Tim's answer.

The "huge space" must be caused by the muscle memory of pressing "Enter" to send but he didn't know that the forum added break-lines instead.

Electrum's "Increase fee" has only the capability to create a replacement that'll send to the same output(s) or back to self through "cancel (double-spend)"

That said, "Cancel (double-spend)" option will replace the output with one of your wallet's unused address.

Is your Seed BIP39 or created in Electrum? (the wallet info in the screenshot is showing "watching-only").

If it's Electrum seed, I'd not bother including the derivation path because Electrum will automatically select the correct derivation path during the wallet restoration process.
The path is already defined in the seed in the form of "version": https://electrum.readthedocs.io/en/latest/seedphrase.html

In case it's BIP39, I'd put the derivation path that's displayed in the "Script type Derivation path" window
and a short list of selections like "Standard->I already have a seed->Options->BIP39 seed" in order for the backup to be "ELI5".

I hope that you have a backup of the unencrypted wallet.dat.
Because by encrypting it while it's not synchronized, the keys for addresses of the transactions that still not saved by the wallet will be flushed and be replaced by new ones.
That may be the reason why you're getting 0 balance in your new laptop.

Try to export the unencrypted wallet to the new laptop instead and let it rescan.

Problem is, that year-2015-transaction should've been already verified with your current block height, are you sure that it's Bitcoin Core's wallet.dat file?
Because you can paste an Altcoin wallet.dat file to Bitcoin core and it will display the previous unverified transactions as Bitcoin until it sync.

In blockchain.com (that's not "the blockchain" BTW) if the address can't be found, it means that it's invalid, not a Bitcoin address;
if it shows 0 in and outs, it means that it's valid but didn't received any transaction yet.

The previous posts are true based from the RBF rules,
but take note that there are clients that will not let your perform RBF if the transaction has a child.

One big example is Bitcoin Core GUI (bitcoin-qt), once your transaction has an unconfirmed child in your mempool, it wont let you select "increase fee" option.
bumpfee wont also work, but it's still possible to manually create a replacement transaction using commands.

They didn't disclose the units in the result of getnetworkinfo but it's in "BTC/virtual kB" on both "relayfee" and "incrementalfee".
That's equal to to additional of +1sat/vB of the original transaction.
When you use the help command for help getnetworkinfo, it'll display the units for those results.

Yours didn't worked maybe because the "absolute fee" is short of a few satoshi to actually reach the minimum of +1sat/B additional fee (like explained by hosseinimr93).
Or if it has an unconfirmed child(ren) transactions, the replacement transaction should be able to pay an additional fee equivalent to the children's "absolute fee" aside from the previous requirement.

Always keep a copy of your seed phrase on a paper stored in a safe place like a vault, that alone can restore your funds in case of lost/broken device.
Do not save it in the same device, online or cloud  storage, or anything that's connected to the internet because of the reason above.

As per security measure, it's a mobile device so it's not recommended for hodling Bitcoins for a long time.
I wouldn't recommend any mobile wallet for that purpose at all unless you won't use that phone.

It's off-topic BTW, next time, please create your own thread if it's not related to the topic.

You must be pertaining about Electrum's "Receive" tab.

Just like others' said, you cannot buy Bitcoins through Electrum directly.
More info for the receive tab: The requests you created using that tab only act as "invoices" so Electrum will know which addresses will be funded so you wont accidentally reuse an address for privacy reasons.
It'll also automatically include the description you input to the history tab when the invoice was successfully paid.
They have expirations because of the same reason so the address for the (unused) expired invoice can be used for a new invoice.
The tab is basically where you request new address to receive Bitcoins.

You can read Bitcoin articles about "difficulty" and "target", the easiest source is the Bitcoin Wiki: https://en.bitcoin.it/wiki/Difficulty | https://en.bitcoin.it/wiki/Target
Disregard the "pool difficulty" parts since it's talking about pool mining.

Basically, if the total network's hashrate is lower, then in the next "epoch", the difficulty will be lower; vice-versa.
More comprehensive details in the link.

Is there any difference if the wallet was created long ago?
Because based from the context, it sounds like newer wallets are harder to crack compared to old ones.

Always base it on that "50% in <n>d".
In your case, It may take more more than 2 to 5 days or if you're lucky, within a few hours if you're lucky.

"bc1qtapr00t" has a quite low difficulty of 34359738368 with VanitySearch (Official Thread link).
That'll only take a few minutes using a modern Nvidia GPU or about an hour with an Intel 4th Gen processor or equivalent.

What I'm saying is, paying $100+ isn't necessary.
