I cannot connect to the smtp server all of a sudden. Have not changed anything lately. Avast is running but disabeling Avast does not help. Receiving mail is no problem. -ISP is ZIGGO. Port is 587 -Thunderbird version is 52.5.2

I tried all given soulutions. Connecting to my account via ZIGGO webmail is possible so password is working.

Best regards,

Albert

Oh wonder......After a few hours things are working like usual! Ziggo denies any problems with their smtp server but I tend to question that ; -).

Thanks for the reply! I found out what the problem is. I use a VPN connection and THAT is the problem. When disconnecting from de VPN everything works perfectly. I tried to exclude Thunderbird from using the VPN conncection but this didn't work either. So disconnecting from the VPN when sending mail via Thunderbird is the only option I'm afraid.
