Lag only in Cross server dungeon (F8)

[Yitz]

As the title states I've been having random hour long daily periods of time where F8 is completely unplayable for me. 2000+ ms but only in f8. Not in mushins tower or farming peaches or TOI. Only arena/battlegrounds/dungeons when entered through f8. Can enter from open world portal and its fine.

Any fixes or something?

Had this issue for the last months not just recent server issues.

OK so I verified I'm not lagging in Arena server. Only battlegrounds and cross-server dungeons.
