What operating system are you using?
What version of electrum is it also? Do you have a firewall enabled, can you try disabling it?
Is your WiFi censored also?
Try turning off auto connect and select a specific node to connect to.
OS: Windows 10
Electrum version: I was using 3.1.2 and I have upgraded to 3.3.2 after facing this problem but still getting it.
I have disabled firewall & windows defender but nothing changed.
Wifi isn't censored.
I have turned off auto connect and connected to specific node but and It say Synchronizing however files size on "wallet" folder won't increase.
Thanks.
