I found out what this error code 112 is, the cause, and its fix. 112 means that the user-specified soft timeout has been reached. The soft timeout argument was introduced by my change 34b0464d7eef; Z3 expects milliseconds and I passed seconds. I'll push the fix later today once I've regenerated the certificates.
Gutes neues Jahr!
