eM Client has no longer access to my gmail

[TThompson]

I’m running into this, too-- but with BOTH EMC & TB!

Em-Client can't "fix" connection-- HELP?

On a working Windows 10 w/Thunderbird. TB stopped sending/receiving Gmail as of 25 Aug. I installed Em-Client for this friend (certain it would solve the issue), but it did the same thing. So, I ran sfc /scannow & dism /online /cleanup-image /restorehealth, no issues. I logged into his Gmail via Edge & it connects fine, so username/PW is correct. I double-checked IMAP was enabled in Gmail settings as well as “allow insecure apps”. It shouldn’t matter, as it WAS working, but just trying everythi…

I even tried to manually set-up the acct. with the settings recommended by Gmail and it simply won’t allow the connection!?
