Some users unable to connect to my server

[oak tundra]

I just updated our server's geyser file with build# 858 and I get the following error when a bedrock player logs into the server. Most of my server members are able to get in still, however I have one member who plays on mobile who gets this error and is unable to login at all.

Found errors in the log!
