I have the same error on csf v7.13 and cxs v5.03
I have installed perl-Crypt-SSLeay that resolved another poster's problem with the upgrade.
Have you had any success in resolving this error?
Would following the install instructions resolve the issue without uninstalling cxs or csf?
I have the US,GB,UK as the country CC_ALLOW_FILTER because I am getting so much spam and this is the only way I can stop it but then I cannot upgrade either.
CentOS 7
CSF v7.60 (which i just manually upgraded from v7.58)
Webmin
Upgrade
Unable to connect to <download link removed so this post works>, retry in 300 seconds. An Upgrade button will appear here if new version is detected.
I tried with csf stopped (to see if the firewall was blocking access, same error.
I can use wget/curl fine from console, dns lookups work, so i think this might be a problem with csf itself ?
I have the same on a new installation CentOS 7 on a vps with csf v7.60 and webmin.
I am using the same setup on another VPS, but with CentOS 6 and do not see the upgrade error. Tried to install the Perl-Crypt but that does not change anything.
Is there a logfile where I can see an error message ? (nothing in /var/log/messages)
