Restrict Google Domain login

L2 Linker

Hello,

I have been using a header insertion to restrict login to an approved list of Google Domains for a couple of years now. However, I have now encountered an issue and was wondering if anyone else had a similar experience or has any idea what to do.

On one of our domains, there is a regular but seemingly random occurrence of login failures with the error message - 

Something went wrong

Sorry, something went wrong there. Please try again.
 
When this happens on a device, it can start working correctly again afterwards with no changes being made. If I disable decryption for accounts.google.com then users can login with any account again.
 
Checking Chrome in developer mode shows that the connection fails going to https://accounts.google.com/_/lookup/accountlookup?hl=en-GB&_reqid=* and stalls when at the initial connection stage. Another device on the same subnet will be able to successfully connect to the above URL and thereofee be restricted to only the Google Domains we allow.
Other domains we have in our organisation dont seem to have the problem, I am struggling to see a pattern that would enable me to isolate the issue. Any help would be greatly appreciated!
