Maximum numbers of connection from user+IP exceeded

Hello,
I needed to copy old emails from Gmail to my Active21.cz domain mailbox. I took emails from a year ago and moved them between mailboxes in eMC. However, after some time, eM Client gives me an error, see img.

What is this problem and how to solve it please?

Hey@Mladek

I do not believe that it is an eMC issue, the limit is being imposed
by Google/Gmail whom I think have a daily maximum.
Try again tomorrow.
If I am wrong someone will say.
This all presumes that I have translated correctly
