Eventually it connects but after a few seconds this happens.

[MCMrARM]

Unfortunately I never tested this on Realms, so I have no idea how to fix it. Does it also happen on xbox live servers?

[NyaomiDEV]

@MCMrARM yes it happens also when connecting to servers

[NyaomiDEV]

It seems it happens frequently when connected to wifi, less frequently when connected via ethernet cable.

[NyaomiDEV]

It should be fixed with this commit and this other one
