hey all,

I get the following error ONLY for internal websites (we have our own Windows CA): SEC_ERROR_CERT_SIGNATURE_ALGORITHM_DISABLED Yes, I could "ignore" the error, however this is not desired. I compared already the algorithm with some external certs (like Let's Encrypt). Same algorithm, no error....

Have already tried with several internal websites, but without success. Some information about the certificate: Algorithm: RSA 2048 key length Sign. Algorithm: SHA-256 with RSA Encryption V3

What is wrong? I have already tried a lot of things without success. Unfortunately, I no longer know what to do.We deploy the certificates (root+intermediate) via GPO (this works so far). We have the above mentioned problems only after switching from 68ESR to 78ESR.

Thanks in advance.
