Party not entering abyss dungeon

When entering an abyss dungeon via party finder, sometimes the party does not enter the dungeon and instead everyone stays where they currently are (it still shows you’re in the party though). Only thing one can do is leave party and try again to make a new group in party finder, but even then it might happen again (today I had it happen four times in a row before we gave up, because we simply couldn’t enter the abyss dungeon due to this bug).

This has been happening for months now and I honestly don’t get how this is not fixed yet. Please take a look at this finally, it’s so annoying.
