Issue

The multiplayer mod is not found in the BeamNG mod manager.
The Launcher shows an error message as the title says.

Workaround

This has to be done everytime there is a new mod release

Visit the BeamMP from GitHub
Download the latest stable (green) “release” BeamMP.zip and place it in your mods\multiplayer folder.

The mod should now be in the mod manager and the multiplayer button available on the main menu.

Possible solution

Follow this guide for a possible solution to the ERROR in the Launcher.

Adding a step that worked for me - as the above didn’t solve it for me…

In powershell / bash i ran “wget https://www.beammp.com” and after that the beamp client was able to connect. All it does is connecting to the server and returning html…So who knows why that helped.

Mozilla Cert Store on Linux discontinued the Cloudflare Root CA. Downgrade to store v310

horrid. dont ever suggest anyone to downgrade anything again.

but thanks, i will use this instead (i am on nixOS):

Manually installing the certs yourself would also be an option.

yeah, i am actually going to try something today or tomorrow, if i will not forget…

security.pki.certificates

and

security.pki.certificateFiles

could potentially do just that, but i will need a .pem file, and i have 0 idea where do i look for one…

…until i found this:

and use the contents of that .pem

You go to the website in question and download the cert from there

oh, thanks! i forgor this feature that is exclusive only to gecko based browsers exists, cos i talked to wis about this a few months ago (a disappointing conversation). strangely enough, i think your browser looks suspiciously chromium-ish! i think there was a mistake, chromium shouldnt have any such features…

but anyway, its useless. it just is. still code 60. nothing changed at all. it is in my distro’s certs bundle. and now - it isnt, because im going to try that pr…

welp…

This is indeed a Chromium based brpwser aka Brave.
Opera GX and MS Edge can do the same.

15

oot.

wowie. that is a lot of steaming garbage you just listed! i hope you do understand that the creator of brave is a bigot?

16

No i did not know. Firefox is also garbage due to their recent EULA changes.
We will now end this discussion as this is an FAQ forum post.
