Nagstamon test build crashes on Apple Silicon

[kelvinvermeulenteamblue]

I'm trying out the new test build as it has web auth built in now. However, on my MacBook Pro M4 Nagstamon keeps crashing (all test builds that I tried). I'm sometimes able to fill in the Monitor (CGI) URLs, but even then when adding a server Nagstamon crashes every time.

This is the crash report my computer gives me:

nagstamon.txt

Any help is welcome, thank you!

Hi @kelvinvermeulenteamblue,

thanks for the report. Web auth is still not stable and I mostly tested it with Checkmk, where it works pretty well now. What monitor type are you connecting to?

Best regards 🎄

Hi @HenriWahl

Merry Christmas first of all, and thank you for getting back to me! I'm trying to connect to Thruk. On my Apple Silicon machine Nagstamon outright crashes (sometimes I'm able to fill in the URLs and extra options, but sometimes it crashes and the window never pops up). For my Intel colleagues, Nagstamon sometimes crashes too, but sometimes they're able to actually make a connection.

But yeah, to answer your question: it's Thruk.

Happy holidays!

Hey @kelvinvermeulenteamblue happy holidays too. Due to them a fix will be a little bit delayed, but maybe you could activate debugging in the Nagstamon settings or start it from source code in a terminal window to get more relevant output.

@HenriWahl thank you for your suggestion! I managed to get it working due to your help. I'll put my findings here, they might be useful to someone in the future.

When I first ran it in the terminal I got this:

During handling of the above exception, another exception occurred:

I then removed the Nagstamon entry from Keychain Access and reran (in the terminal), and now I got it working:

Getting it to load properly by double clicking Nagstamon in my applications folder is still an issue, and the screen can be quite buggy at times, too. Nonetheless, I managed to authenticate via Web for a Thruk monitoring type!

Thank you for your help!

What a Christmas 😁🎄
