POE2 Portal Warning (Trial of Sekhemas)

Man this sucks, just happened to me before i ascended. How do I even get a new token to start over?

Yeah I just had this happen to me. Sucks, I had a good run on a fresh hardcore character with 3 silver keys and a gold. I got a trade whisper so I went back to town to do that because my inventory was full anyway, so I invited the guy, traded, and tried to go back but the portal was broken. I fast traveled back to area with the waypoint but when I touched the alter it just wanted me to put a new coin in so I think I just got screwed. At least I grabbed my ascendancy points first...
