SMServer crashes on login

[FoleyDiver]

Problem description (steps to reproduce):

• Open SMServer.app
• Start server with green play button
• Open web interface from laptop (leaving the app open on my phone)
• Input password
• App crashes on my phone, and the web interface gives me an error modal about the websocket cert not being trusted (it tells me to go to port 8740 but I can't because the app/server has crashed)

Details:

• iPhone SE 2016 (MLMD2LL/A)
• iOS 14.1
• Jailbreak: checkra1n
• SMServer installation method: cydia -> repo.twickd.com (not sure if this is important, but I had to mirror the .deb to my own personal repo because twickd kept blocking my IP after a few minutes)
• Version: 0.8.0
• libMRYIPC 2.0.1 (from BigBoss repo)

Sorry if I missed anything, please let me know if I can add more info.

Thanks for this amazing app, I'm excited to try it out!

So normally this error means that the IPC process (which is necessary to send texts, get pinned chats, send read receipts, etc) isn't running, so just to make sure: Did you run an ldrestart or userspace reboot after installing SMServer? If not, could you do so and try again?

[FoleyDiver]

I didn't do anything like that explicitly (i.e. unless Cydia did it for me it didn't happen). Per your advice I ran ldrestart on the phone and that seemed to do it, Thanks!

Btw does userspace reboot = respring? Or are they different things? I've never heard of it. I try to keep my reboots to a minimum because it means I have to re-jailbreak.

Edit: I found this reddit thread explaining it: https://www.reddit.com/r/jailbreak/comments/axto2f/discussion_what_is_ldrestart/

I guess this issue can be closed. Thanks again for your help!
