Kerberos Problem sporadically with some user and Chrome and Edge (chromium)


We use Keberos Auth on the F5 in an APM Policy for many years and for thousands of employees every day and it works all the years with IE and Chrome.


Starting last year we see isolating report of problems with “Page cannot displayed” after working hours on the PC and a break (idle timeout) but also sometimes in the morning but in all cases it works basically.


That has changed in the last weeks and together with the need of many web applications for the new Edge based on Chrome we have many cases where user cannot work.


We checked all, but also in Debug mode, all we see is that the "Kerberos Auth" fail, in addition, the Parameter log.rba.level (K24065228) will not give more information.


It may be no problem of f5 but we see no way to find the reason without a detailed error message.


Anyone with similar experiences and a solution?


At the moment we guess around encryption
