p2p/sig no_session(expired auth from discovery)

Hi, I was trying to enter the realm that one of my friend from ps5 created. He invited others friends in his realm; 2 from ps5, 2 from ps4 and 3 from pc. When we were trying to enter the realm the error message "p2p/sig no_session(expired auth from discovery)" appeared. Is this still a problem or do I need to do something to fix it.
