OK, it looks like this problem is only with the "Check now" button.

The release status of the qm-dsp has been updated OK automatically next day.

The "Check now" button works for me on qm-dsp. Do you still see this issue @valtri?

The failure of 'http://dl.hexchat.net/hexchat/' might be related to this:

Most of the failure with https are related to invalid certificate(s)

The "Check now" button doesn't show there, but that's not critical (it may be feature - check is not needed when checked recently). The update check of qm-dsp looks OK. I would consider this part as solved. :-)

The hexchat: there is used http:// at https://release-monitoring.org/project/1313/. The certificate looks updated (it contains *.hexchat.net in altnames), maybe it could work now.

Apparently this does not cover dl.hexchat.net:
requests.exceptions.SSLError: hostname 'dl.hexchat.net' doesn't match either of 'ssl2000.cloudflare.com', 'cloudflare.com', '*.cloudflare.com'

It is strange, that chromium and firefox accept this certificate, but curl and python-requests don't...

The pull-request mentioned above fixes this issue by allowing to make insecure http calls.
