Apache not starting error ca md to weak

[overflower83]

Last night we updated our apache to 2.4.52 and since then apache won't start
We get the following error:

[Thu Dec 23 10:00:02.258524 2021] [ssl:emerg] [pid 2512:tid 140170817459008] AH02562: Failed to configure certificate localhost:443:0 (with chain), check /etc/httpd/conf/ssl.crt/server.crt.combined
[Thu Dec 23 10:00:02.258566 2021] [ssl:emerg] [pid 2512:tid 140170817459008] SSL Library Error: error:1415A18E:SSL routines:ssl_cert_add0_chain_cert:ca md too weak
AH00016: Configuration Failed

We have looked at the settings and cannot find any reason why this is failing.

Anyone any tips?

We also checked the server.crt.combined to check the signature algoritm using the below command:

openssl x509 -in /etc/httpd/conf/ssl.crt/server.crt.combined -noout -text | grep 'Signature Algorithm'

The output is:
Signature Algorithm: sha256WithRSAEncryption
Signature Algorithm: sha256WithRSAEncryption

And this should be ok.

We found a solution our selves.
After regenerating the service certificates using the following article:

We could start httpd again.
