HTTP Error Code : 400
The issue is API system link. It is not our problem, it is about our client.
Hubspot ID is 2937108.
It started about 2~3 weeks ago.
Whenever logging in, Server error message appeared.
It seems that it is not related to external connection.
and HTTP Error Code is 400.
Our client never revised. We checked history.
I think it is related to technical support team.
Thank you in advance.
