hello
i have electrum Version 3.1.3,
it has been more than week and i cannot broadcast any transactions, every time i get : Server did not answer, even when i try another servers.
that's strange it is working very well for me, try to check your firewall.
is there any way to broadcast electrum exported signed transactions or any way to fix this issue.
You can send the tx to the receiver via email 8-), He will push it for you if he want to get his money, or
if you only want to push a tx you can try this service. I have never tried it, but I hope it will work.
