Setting the MT Enhanced Plugin for Trados Studio (6.0.0.2) does not succeed

I tried to set up the above plugin according to

 MT Enhanced Plugin for Trados Studio .

After entering our google API key which we were using for TRADOS Studio 2019, I clicked [OK].
But, the following error was displayed and the API key could not be saved.
"The provided API key has an IP address restriction. The originating IP address of the call (xxx.xxx.xxx.xxx) violates this restriction.
Could you tell me how to handle this problem?

Regards,
Aki
