Since May 1st, 2026, two of my servers are emailing these errors: Subject: Cron <root@server2> "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null [Fri May 1 10:34:24 AM EDT 2026] Please refer to https://curl.haxx.se/libcurl/c/libcurl-errors.html for error code: 28 Server2 has emailed twice (May 1st, May 5th) Server 3 has emailed twice (May 2nd, May 3rd) I have two other servers that so far, are not giving me this error via email. All boxes are Debian 12 and during the first week of the month I always do a: apt-get update && apt-get upgrade My version of ISPConfig is 3.3.0p3 Should I updated to 3.3.1p1 ? Thanks.
