Describe your issue

Downloaded fresh server pack and fresh modpack install and only messed with EULA and ipproperties to join from separate machine. Currently when joining from separate machine the sever is telling me that the mods are mismatched. Fixes I've tried is that I noted the sever mods folder has 251 mods while modpack mods folder has 271 so copy and pasted 251 mods into my machine that is joining the sever, still says incompatible got to join once but subsequent times did not let me join. Another thing to note is when loading the modpack from seperate machine I see it loads 252 mods when I have only 251 mods in the mod folder.
Pictures is what I see when joining from my separate machine

Steps to reproduce the issue

Install server pack change server properties to IPV4 and EULA agreement to true Install modpack on separate machine Join sever from separate machine using public ip address that has port forwarding already set up

Additional Information

latest.log Only messed with line that had my public IP address

[DoctorMage]

ignore the mod mismatch (this is due to forge not checking for purely client side mods) and server mod count as client will have client side mods that the serverpack does not need

step by step how are you starting the serverpack

[DoctorMage]

and does the console show you attempting to join the server when you click join

Running through the steps per your comment

step by step how are you starting the serverpack Extract Sever modpack Change EULA to true Edit Server.properties to add IPV4 Edit LaunchSever.bat to: java -Xmx5000M -Xms5000M -jar forge-1.16.5-36.2.39.jar (Just because in my experience my minecraft severs don't recongnize Gig ram sizes but that is different thing entirely) Run LaunchSever.bat application

With fresh pack install on separate computer I input my public ip address to test connecting Seems to fail to connect the first time then join the world the second I did not change anything from what I was previously doing but I can repeatable join and disconnect from my sever now.

Yea maybe it was issue of trying again and again or it works today with fresh sever pack and modpack
