Topic: HTTPS/SSL Certificate Error DLG_FLAGS_INVALID_CA

[Valeriobi]

Hello all,
I'm trying to work this out, but I will need some help from you guys.

I'm running apache2 on Debian 9, the apache web server is behind an f5 big Ip that does load balancing and manage the SSL encryption and decryption for the apache web server.

The certificate is installed on F5 but when I try to reach the web page I get this error:

"Your PC doesn’t trust this website’s security certificate.
The hostname in the website’s security certificate differs from the website you are trying to visit.
Error Code: DLG_FLAGS_INVALID_CA
DLG_FLAGS_SEC_CERT_CN_INVALID "

in the certificate the domain assigned is *.mywebsite.com

on the apache2 web server I've tried the following:

in apache2.conf I've tried to define
ServiceTokens FULL
SecServerSignature "www.mywebsite.com"

In /enabled-website/000-default.cof:
ServerName mywebsite.com
ServerAlias *.mywebsite.com

but still throwing that error, could you please help me with this?

Regards,
Valerio

Did you try clearing your browsers cache?

Hello, Thank you for your answer, I've tried the cache already but did not work, any other suggestion?


Can you please confirm that my apache server conf is correct as discussed in the first post? At least I will be able to focus on the real issue.
