Launching electrum wallet in realized it probably is connected with SSL certification failure but i have no idea what caused it and how to resolve it.

Code:
I/n | network | connecting to XX.X.XX.XX:50002>:s as new interface
I/i | interface.[XX.X.XX.XX:50002] | disconnecting due to: ConnectError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)'),)
I/n | network | couldn't launch iface XX.X.XX.XX:50002:s -- CancelledError()

I have set electrumx server in docker on this machine previously (it worked properly) but than i wanted to have it locally (but after unsuccesful attemps)  i made loop back to docker. Maybe the fact that it had other cert assigned previosly has to do with this?

Can you try to remove the pinned certificate from this location %appdata%/Electrum/certs

I just got the solution from Electrum GitHub page here "Error SSL Certificate verify failed"
He solves the issue by removing the certificate from the Electrum cert directory.

Thanks, but you mean on client side right? Would you know where to look for it on linux? I was browsing /etc/ssl/certs but didn't find anything with electrumx.

EDIT: i manage to found this cert it was in my home directory but shadowed. For me it was in /home/user/.electrum-ltc/certs

Thanks for help!

Thanks, i finally ended up with setting it with docker. But i still have other problems..

For me server looks like it synced, i saw that it caught with most recent block and it's displaying logs:

Why not use the alternative ElectrumX which is developed by spesmilo of Electrum?

You can get the ElectrumX from their Github page here https://github.com/spesmilo/electrumx

Did you run this on VPS server/raspberry pi or you are running it with your own PC/laptop?


Look at this below
- More developers abandon work on BTC—this week it’s ElectrumX

This might be the reason why they remove the Bitcoin on ElectrumX

Thanks for pointing that out that was for sure main problem. So  i took your advice and installed server with altcoin support. Unfourtounatly now i get this:

Code:
Jul 27 14:59:58 dev-electrumx-ltc electrumx_server[17384]: Traceback (most recent call last):

but aiorpcx is installed:

$pip3.7 install aiorpcx

Code:
Requirements already satisfied: aiorpcx in /usr/local/lib/python3.7/site-packages/aiorpcX-0.18.4-py3.7.egg (0.18.4)

 I saw some github issues related to this topic but could't found anything resolving mine.

Too bad, kyuupichan's ElectrumX now only supports Bitcoin SV [BSV].
You can check the code itself: https://github.com/kyuupichan/electrumx/blob/master/electrumx/lib/coins.py#L268, there's only BSV and its testnet/regtest there.

You can use the older versions (1.14.0 and below) though: kyuupichan/electrumx/releases or the Altcoin branch: https://github.com/kyuupichan/electrumx/tree/altcoin
