I just installed Thunderbird recently, went through some hoops to get my two Gmail accounts receiving mail. when i went to send an email from one of them: SMTP timeout error. thought id test by sending some test emails to my other accounts: timeout error, thought it was something wrong with my Gmail settings.

Out of curiosity tried to send an email from my outlook account to my gmail accounts, same SMTP error.

Went to troubleshoot, double-checked all my SMTP setting for all my accounts, tried deactivating my firewall, safe mode with internet won't let me use Wi-Fi (I'm on a laptop with no wired connection available), tried setting min TLS version to 1. SMTP timeout error

what am i missing?

If you are using ESET/NOD32 security/AV there is high probability it is causing your problems. According to ESET forums, you should temporarily disable SSL on ESET until they solve the problem per https://support.eset.com/en/kb3126-disable-ssl-filtering-in-eset-windows-products?ref=esf - the problem is being reported by dozens of users https://forum.eset.com/topic/26517-problems-with-thunderbird-and-imaps/ https://forum.eset.com/discover/

I'm not using ESET personally, but you might be right since the problem kind of disappeared this morning...
