Electrum Wallet Won't Connect to Server on Ubuntu 18.04

[Plague1908]

I have just downloaded the latest version from the official website 3.3.4 onto my desktop running Ubuntu 18.04. For troubleshooting I have tried connecting to recommended servers, manually connecting to a server both times disabling auto connect feature. I have also tried resetting my router in case there was an issue there. Nothing has worked.

In my initial install I successfully verified the signature so I am confident that no phishing version was accidentally downloaded (again I went to the official website for the download). I am new to having a bitcoin wallet but I have been using Ubuntu for years so a terminal command install was relatively uneventful. I purchased some bitcoin (ATM cash) only to learn when I returned home that when attempting to connect to the network it will either say "synchronizing" or not connected at all (when I tried to connect to different servers). I have confirmed at Blockchain that the transaction was successful and that the address I own correlates to where it was sent. No one has taken the bitcoin.

I am at a loss. What else can I possibly do? I am seeing posts where people claim it is tricky even dangerous to download a new wallet and I don't want to do that anyway. Have I missed anything else? What causes the wallet not to connect to the servers? Any help would be very much appreciated.

There could be various reasons for your electrum wallet not synchronizing properly. More commonly electrum wallets won't sync when you have an older version of electrum running in your OS. This doesn't seem to be the case for you since, you have installed the latest version of the software.

The second one is that, certain Electrum servers have to be connected throught the port No 50002 for receiving SSL Connections. If the electrum operates in a TOR Based server then Port No 500001 should do the work.

Though I have never used Ubuntu to guide you in a right way, but I have seen people commonly saying that Linux and Ubuntu OS seems to be blocking the electrum access to its servers by blocking the Ports 50001 and 50002 using the firewall option present. So, you need to install Gufw Firewall from the official website and need to configure them such that, your Ubuntu OS allows your Electrum Software to connect to the Port 50002 or Port 50001 (if you are interested in running using a TOR Service)

You need to Note that, if you are using the server to connect through TOR based service you need to specify 50001 because using SSL via TOR doesn't actually make sense.

It's mostly connectivity issues. Try starting your Electrum with VPN or dnscrypt. I'm using the same Ubuntu as yours and it's fine here, standard setting since I installed it.

Run electrum using the terminal with the -v switch, paste what it outputs on pastebin.com and share the link here.
