Forge/Vanilla Internal Exception java.ioException : An existing connection was forcibly closed by the remote host

Dear forum members,
for some time now we have been creating and maintaining new ways to help game server admins with questions and problems as quickly as possible, e.g. our Guides section and the Nitrado Community Discord.

Therefore, we inform you that the Nitrado Forum will be closed on March 31, 2023. We are consolidating our community support to our Discord channel, which is faster and more efficient. We have also seen incredible growth in our community due to the hard work of our moderators and our bots. We are confident that this move will ensure that we provide the best support possible for our users.

Thank you to all members for your continued use of the forum!

Assistance with all questions concerning your Nitrado service can now be found in these spots:
Community Discord: https://discord.gg/nitrado
Guides section: https://server.nitrado.net/guides

    Since a few days I cannot join my Minecraft server or if I'm able to join I'm getting kicked after a few seconds.

    Sometimes I'm not getting kicked, but then even though my Internet is working fine, it's so laggy that it's almost unplayable.

    It's working fine for my friends, but 2 of my friends encountered that same problem a few weeks ago, but now it's working fine for them.

    I have literally tried everything, from resetting the Minecraft server till reinstalling my Minecraft. I even tried using an VPN which made it playable for a few seconds before getting kicked. Also when getting kicked this message comes up (Uploaded it).

    I have searched in the Internet, but it doesn't seem to have an solution yet. Some were saying that it's just the "low quality" nitrado servers, which made me think of switching hostes, what would be a real pain in the ***, but if it's not working otherways it's the only option.

    Hope to get a solution soon, or just a simple reply from the staff, because my patience reached it's limits.
