"Invalid URI: The hostname could not be parsed" error when trying to sync with a gmail calendar

Version 7.2.35700.0
It was fine the first week and now getting the “Invalid URI:
The hostname could not be parsed” error when trying to sync with a secondary gmail account. The account I’m trying to sync calendar is [email protected]
I had added it as a new account (Calendar Only)

Help! and Thank you!

You could try removing that account from eM Client, then adding it again.

Otherwise as a Pro License user, please make use of your VIP Support option and open a support ticket with eM Client. They will be able to assist you further.

I have deleted my account from eM Client as suggested and added again. Same error messages.
