I see the same issue.
I had to checkmark the
"Allow legacy signatures in handshake" in the certificate verification.
Are you running 126.96.36.199? I don't seem to have that option.
188.8.131.52 removed 6 signature hash algorithms. 184.108.40.206 adds 3 back if you select the option to Allow legacy signatures in the handshake.
It's possible to get the pcbtax site working on 220.127.116.11 by configuring the certificate verification settings so that TLS 1.1 is the strongest option selected in the alternative handshake settings. When this is done, the initial handshake using TLS 1.2 will fail and the attempt that uses TLS 1.1 will succeed.
This doesn't help for the epsoninsider site because that site only supports TLS 1.2, but it will work if certificate verification is configured with TLS 1.2 selected and Server cipher list: TLSv1.2:!DSS:!DH:!NULL:@STRENGTH
