[Electrum 3.3.8] Not connected to network on multi signature wallet

[estrox]

Hello. My electrum wallet cannot connect to network / sync with the blocks around this 1 year.
I read older / similar posts and try to solve it but still happen the problem.

[Environment]
・Windows 10
・Electrum 3.3.8
・Multi signature wallet (2 signatures needed in 4 wallets)

[Tried things to solve it]
・Change setting on servers from automatically to manually (Choose some of servers manually) -> not sync.
・Delete "blockchain_headers" file and restart electrum -> not sync.
・Restore the wallet with the seed as standard wallet -> not sync and my addresses are changed.
・Restore the wallet with the seed and 3 xpub keys as multi signature wallet -> not sync and my addresses are changed.
・Uninstall Electrum and re-install latest one-> not sync.
・Uninstall Electrum and using stand alone one -> not sync.

So, what should I do next...?
Please advise me, thank you.

These aren't necessary, in fact #1 will even make it seem disconnected until you've re-downloaded the headers.

Try to disable your firewall and/or AV temporary to see if its blocking your connection.

If disabling the firewall worked, create an exception for Electrum, then enable your firewall.
If disabling the AV worked, create an exception as well.

When you say it won't "sync"... what exactly is happening?

Are you getting "green dot"?



"red dot"?



or "blue arrows"?



Do you see a message in the bottom left saying "Synchronizing"?

Thank you for your advice!
I disabled firewall but it still not connected... however, I added exception just in case.

Ah sorry and thank you for pointing out it.
I used to use Electrum in Japanese so the word was ambiguous. I changed it to English.

My status is,
"red dot". In addition, in the bottom left saying "Not connected".

There's small possibility your ISP block port used by Electrum server. Have you tried using proxy, Tor or VPN to connect to Electrum server?

Ah Yes! I've tried using proxy on Electrum(Tools -> Network -> Proxy) to resolve the connection problem.
In the case, how should I do?

There are two ways to do it. Scroll towards the end for instructions on how to do it for your Windows OS.

Thank you for your advice. I tried to use Electrum through Tor with below command according to the url:
' "C:\Program Files (x86)\Electrum\electrum-3.3.8.exe" -1 -s electrums3lojbuj.onion:50001:t -p socks5:localhost:9050 '

However, the problem still happen. Bottom left message says "Not connected(proxy enabled)" and still turn on Red dot on the right corner.

in the similar old topic, I saw someone advised that exporting private keys into Coinomi wallet... Should I try it if it not have risks?

Do you actually have Tor installed and running? It is not built into Windows, you need to download and run Tor from here: https://www.torproject.org/download/

Exporting private keys has many risks. I would not advise that you do this at this time. Your best option is to figure out why Electrum is unable to connect to the network and rectify the problem.

Have you tried to add DNS it might be because of your ISP or the DNS that blocking your Electrum from syncing?
Try to add DNS from your PC(ipv4 settings) put 8.8.8.8 and 8.8.4.4
Then test it again.

If you have an android phone you can try to test Electrum on your phone. If it still blocked from syncing the issue is under your network/ISP not the wallet itself.

If you are going to use Coinomi wallet for desktop it will not be safe.
Like the above said much better to solve this issue rather than exporting it to Coinomi wallet but if you still want to export your seed to other wallets I recommend you to use the Electrum mobile instead.

Thank you so much, using Google public DNS (8.8.8.8 and 8.8.4.4) solved the problem!
My ISP or DNS may be blocked....but now, My wallet works correctly.
I appreciate your and others kindness!
