Unable to Connect with World Error

I am trying to play Minecraft with my friend using free joinable servers. I am on PC and she's on Nintendo Switch so we are using cross-platform. Whenever me or her try to join one another we get a error that says "Unable to connect to world". We are able to connect to other realms, we have good internet, we have both uninstalled and reinstalled Minecraft, we have both restarted our devices, my firewall is allowing Minecraft. There are probably more things we have done but that's all that I can remember. This is day 2 of this happening so this isn't just servers being down. I have looked EVERYWHERE for a fix and none of them work. If anyone knows what me or her can do to fix this I would be very pleased.
