Hi @Hardeep123 ,

What type of cert are you guys using? Is it self-signed or from a trusted CA? I would double-check and verify the Portal/GW cert is trusted by your linux clients.

Hi @JayGolf

Its a self signed certificate, same certificate is working on Ubuntu version 20. pls suggest.

I saw multiple post and solutions on the forum, but afraid to try as that could interrupt my entire services, although few steps tried which were pointing towards Chrome SSL errror
