Windows server ssl problem

Hi,

I have setup a linux server with a certbot ssl certificate.
When i access the website erom the server on different PC's everything is fine and the certificate is valid.
When I try tot access it from a Windows server i get the warning that it's not safe to visit the site. The issuer of the certificate is also different from on the other PC's, it says cendo02-fw01.belbone.local.... In stead of R3.

Could this be a firewall issue? There is a barracuda firewall in front of the server.

Any suggestions?

    Hello @HvH

    Yes, this could be a Firewall, proxy or DNS routing issue. As the domain goes, it may seem that has something to do with Belbone, which is a Belgian ISP. It could be possible that traffic is filtered at some point for that ISP or it provides overlapping information for the certificate request.

    Hope this helps with your query,
