I am new to this list, please forgive me if I am submitting the following to the wrong place.

We've just installed pgAdmin4 web on RHEL7.9.
Once we started the httpd service, we couldn't login the system, the webpage spins forever.
The error message is attached below.
The RHEL 7.9 we use has FIPS enabled, e.g. cat /proc/sys/crypto/fips_enabled has a value of 1.

It seems the version of pgAdmin4, 6.21, still uses MD5, which is not allowed by FIPS.

I'd highly appreciate if anyone could let us know:

1. Is there a version of pgAdmin4 on RHEL 7.9 that supports FIPS?
2. Is there any plan down the road that pgAdmin4 would support FIPS on RHEL 7.9?
3. Is there any way to get around the issue?

Many thanks in advance,
