Sectigo RSA Domain Validation Secure Server CA removed?

Hello Quallensaft,

How have you realized your firewall lost "Sectigo RSA Validation Secure Server CA"? is that during any firmware migration ? which SFOS version you're using ? It's unlikely that SFOS have added and removed this certificate. 

Could you IM with support access ? to check what might have happened here.

Well would be cool to know if Sectigo RSA Validation Secure Server CA is default on the firewall in first place?
And if the firewall needs the complete CA chain to verify certs issued by Sectigo RSA Validation Secure Server CA?

I did nothing regarding certs. Since today I got cert validation errors because Sectigo RSA Validation Secure Server CA is missing.
XGS 3300 latest firmware.

No it's not, that's the reason why I wanted to understand how it came in (i.e. manual upload?) and how it wiped off (need to check) 

I uploaded Sectigo RSA Validation Secure Server CA by hand to get the issued enduser-certs working.
Without I get a cert-error that it's not trusted "Blocked due to invalid TLS certificate".

I just wonder because a lot of websites using certs issued by RSA Validation Secure Server CA and until today I got no errors. It was also not necessary to upload it before.

So I assumed that it was on the firewall before…

Could this certificate be issued by the old CA? 

Can you link us the link of the URL, you saw the problem?
