Description

This article provides some workarounds for HTTPSD crashes with ACME enabled.

Scope FortiOS 7.6.3.
Solution

There is a known issue on 7.6.3 GA - ACME can trigger the HTTPSD process to crash.

 

First, verify whether the issue matches the known issue by executing these commands:

 

get system status
diagnose debug crashlog read

 

Crash-log snippet to compare:

 

2025-06-16 11:38:18 <10313> firmware FortiGate-60F v7.6.3,build3510b3510,250415 (GA.F) (Release)
2025-06-16 11:38:18 <10313> application httpsd
2025-06-16 11:38:18 <10313> *** signal 11 (Segmentation fault) received ***
2025-06-16 11:38:18 <10313> Register dump:

 

If the outputs are the same as in the snippet above, and if there is ACME already configured, further steps can be followed as a workaround. Make a configuration backup, then apply these workarounds:

 

  1. Execute this command in the FortiGate CLI:

 

diagnose sys acme purge-all

 

  1. If the first step fails, run the following commands:

 

config sys acme
    unset interface
    unset source-ip
end
