The DirectAdmin already patched CURL version to fix this bug. Please update CURL:
This error occurs only on servers with the DirectAdmin control panel after the CURL version update from DirectAdmin end to 7.82.0 which affected by the bug described here: https://github.com/curl/curl/issues/8559
You can check the CURL version with the following command:
[root@directadmin_test ~]# curl -V curl 7.82.0 (x86_64-pc-linux-gnu) libcurl/7.82.0 OpenSSL/1.1.1k-fips zlib/1.2.11 zstd/1.5.1 nghttp2/1.46.0 Release-Date: 2022-03-05
On servers with the DirectAdmin control panel, the version of the CURL is managed with the CustomBuild utility, replacing the system origin CURL.
