Photon bolt network issues

Hi, I've been using bolt in my game for a while, however after releasing my game some of players have connection issues.
I'm using the relay also.
Some of the users have problems connecting to others, they get AM: Received Error From Zeus: Can't connect to host 44703d4d-5162-49e0-91af-1b0ff4d29328, it does not have a valid WAN end-point
And nothing more happens. Shouldn't relay deal with this after zeus fails and connect the players?
