The host has a 12 year old CPU Intel Xeon E5-2630 . Together with argon2 as passwordhash there is a problem. As soon as I switrch to SSHA everything is working fine.
Can someone confirm it?
Another possibility... Disassemble the instructions around 7febaf26a415, and then post the snippet. Then we can see if the instruction is available on the processor.
If I recall correctly, Argon2 provides several implementations, including straight C. A C implementation should run fine on the processor.
(Debian's base machine is just x86_64, so there's no extensions other than SSE2. SSE2 is available on all x86_64 processors).
