My can't connect to the server

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:

  • Hallo guccicake,

    please open your Minecraft Launcher -> Settings -> open output log as soon as the game starts -> activate

    Now a log should open while playing.

    Is this possibly what is happening in this log? Maybe a mistake / error?

    With friendly greetings


  • The Technic Launcher should have such an option. Look, if you can set the launcher, somewhere they have hidden such an option. :)

  • This problem is only a problem with Technic Launcher

    A list of all installing modpacks in the Technic Launcher and on the server with version would be helpful.

    Did the problem occur after an update?

    Did the problem exist from the beginning?

    Another helpful way would be to look at the logs that are being created. I found a German "manual" and translated it with the translator:

    "If this does not help or has already been changed, please go to the Technpack on the Modpack, what you want to play and always crashes. Now you have a point in the top right "Modpack Options". Please click this. It opens a small window, where at the top is an input line "installation order". Behind it is a button "Open". Please click this.

    It should now open an Explorer window and jump directly into the folder of the modpack. Here you go please in the folder "logs" and attach the files "latest.log" and "fml-client-latest.log" to your post." [Technic Launcher - Hilfe - Minecraft Forum]

  • Which log is that?

    Which mods did you install in the launcher?

    Is there an error in the server log?

    Unfortunately, I'm not familiar with the launcher. So these are just general questions.
