SOLUTION: You need to review all your mods that you know that have configuration files, usually when changes are made that require you to apply them on your server to make the mod/server working again, are reported by the mod devs, read their changelogs, check the wiki, Steam Workshop page or Discord, usually all the information you need it's reported there.INCOMPATIBLE MOD CONFIGURATIONS - On some updates mods like Expansion, Trader, etc change their settings files with new entries, or even with new files.SOLUTION #2 - Check the most obvious mods, those mods that you see that are not very popular and not very well maintained, there are a thousand mods on Steam Workshop, but a lot of them are just abandoned mods, they get released on Workshop and then abandoned and not updated anymore, when a big DayZ update releases, those mods stop working, you need to check all your mods one by one if needed, see the last update date on Steam Workshop, read the description of the mod if anything related to mod broken or being updated anytime soon, and the commentaries, most times other users report if the mod it's broken or not on the commentaries.SOLUTION #1 - There's not really an easy way to tell what exact mod it's broken in the middle of the dozens of the other mods, the best way is to check the server logs, start the server, wait 10 seconds and press the Web Console button, sometimes it gives the reason why server not starting in the form of error on the last lines of the Web Console, you can also check the server_console and script_log inside Log Viewer button, sometimes those logs also give some hints about broken mods preventing the server from starting.BROKEN MODS - On big DayZ updates a lot of mods break and prevent the server from starting after the update since mods are not compatible with the new update.SOLUTION - Go to the MORE button and run the Force Steam Update button, which will force update DayZ.STEAM UPDATE FAILED - Sometimes Steam gets overloaded with everyone updating at the same time and the update fails.
