--- Comment #11 from Martin Stangl <martin.sta...@t-base.pro> --- I tested with 2 other client certificates. Same result. Let's encrypt certificate with OSCP.

But I can confirm that no related calls to the internet where done when using the certificate issued by the Active Directory Certificate Service. I will try to do some more snooping, but it will take 2 to 3 days until I get to it. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
