PokerDom Casino: slot malfunctioned after the bonus round triggered

A few days ago I was spinning the 3 OAKS slot 3 Clover Pots, and at some point I hit the bonus game and the slot crashed at that exact second. When I tried to re-enter the slot it loaded for a long time, then the message “Server unavailable” popped up. Trying from my phone didn’t change anything. A couple days later a friend was visiting, I asked him to open it from my PC, from the same browser and the same link, and from his account the slot loaded fine. I wrote to Pokerdom support, but they replied about cache, ISP and V@N. Even though I understand the problem is clearly not on my side – because if it were, the slot wouldn’t have launched from my buddy’s account either, which I told the operator – I still followed absolutely all their recommendations. After none of the suggestions helped, when I asked why the slot works only for me, I kept getting the same answer about V@N, and then the operator even went offline. The second and third operators didn’t say anything new and the problem wasn’t resolved. The page code shows the same 503 error when launching the slot, so everything points to the block coming from the server.
