SMTP Fails with GMail on MacOS/IOS
I currently utilize 2 GMail accounts on with IOS and MAC Mail. One of the accounts has just stoped working for SMTP. The other account works fine.
The effect is is the same on both IOS and MAC.
"Cannot Send the Message Using the Server xxxxx.gmail.com" - MAC
"Cannot Send Mail. The connection to the outgoing server smtp.gmail.com failed" - IOS
I have tried all the usual remedies.
Remove 2 Factor Auth
Enable Less Secure Apps
Deleted and Added back the Account
Set up the account as IMAP Only
Cleared Captcha.
All without effect.
The logs from the connection doctor indicate the following.

501 5.5.2 Cannot Decode response e10sm3749582qtx.66 - gsmtp
Then it fails with too many login attempts.
Every now and then, the account will work again for a short period.
Downloading the GMail app for IOS works correctly every time.
Using the Web App for GMail also works fine.
Any help would be appreciated.
