The first clue here is that disabling HTTP2 profile resolves the error, and the APM login page is served correctly again.

 

My suspicion is some combination of multi-domain authentication, and HTTP2, broke in 12.1.3.4

 

It is still broken in 12.1.3.5.

 

I've got the contract people sorting out how to raise this issue with F5 properly.

 

Anyway disabling HTTP2 may be an answer, even if it is not a good answer.
