Could not contact registration server

Since I restarted the service today my registered FOP2 is running in DEMO mode. If I do "fop2_server --test" I get:

# /usr/local/fop2/fop2_server --test
Flash Operator Panel 2 - Invalid license for this install (hostname mismatch)
Running in Demo Mode

Even though, I'm pretty sure the hostname was not changed. As mentionned in this tread:
I tried to revoke the license and got this:

License Revoke
Enter your serial code: xxxxxxxx
Could not contact registration server, please try again later. at /loader/0x24f1be0/FOP2/ line 356, <> line 1.

Any idea?

    I saw this article:
    Not a problem on my server:

    No iptables rules either

  • try this command:
    /usr/local/fop2/fop2_server --revoke --rp=http
    same to register, /usr/local/fop2/fop2_server --register --rp=http
