Hello,
I was in a Party for HM-Vykas (Gate3) and during the fight I had a disconnection from the server. When I reconnected, the boss was dead and I had no loots or rewards.
Server : NA WEST - AKKAN
Character : Pupae
Hello @JANG28,
I am sorry to hear about your lost entry and therefore the reward based on getting disconnected near the end of a run but please bear in mind we do not provide re-entry tickets in cases not caused by a verified server crash or outage.
We’ve set up a system that will automatically reissue entries in scenarios caused by a verified server crash or outage within 48 hours. That is to say, if the system does not reissue your entry ticket automatically on this occasion, we will not be able to do so manually. You can read on how we handle these scenarios here.
Hope this helps and see you in Arkesia! 
same here , got disconnected from the server (eac offline) while doing vykas and lost the entry ticket
server : NA WEST - SHANDI
