Since ProtonVPN ‘help’ desk only advise me to keep trying an unspecified number of US and ex-US servers, I’m posting this here in case it is better known to Librem One users.
In the last few weeks, SMTP hangs when ProtonVPN is connected. As soon as I disconnect ProtonVPN, I can send the mail. This is a new problem, and I have made no changes to the default configuration I get from Thunderbird. Receiving mail is unaffected.
Advice on troubleshooting also appreciated. Are there logs could I inspect?
