SSL/TLS Certificate
tpnet.pl
tpnet.pl has no A or AAAA record, so there is nothing to connect to at https://tpnet.pl. This is the certificate served at www.tpnet.pl.
Certificate problem (wrong host name)Expires in 36 days
The certificate is for *.orange.pl, orange.pl, www.orange.pl and 1 more, not www.tpnet.pl. The server is handing out a certificate for a different site; this happens when a site on shared hosting or a CDN has no certificate of its own, or when www.tpnet.pl's DNS points at the wrong server.
Fix: Install a certificate that names www.tpnet.pl, or check that www.tpnet.pl's A and AAAA records point at the server meant to serve it.
