Can't access webserver from other computers on the network

Troubleshooting
1

Hi,

I can’t pinpoint exactly when this happened, but I can no longer access cryoSPARC web server from other computers on the network. Port 38000 is open and web server works fine on localhost. I tried restarting the system - still the same issue.

Hi Mike,

Sorry to hear about this trouble. As far as I can see, there have not been any code changes in cryoSPARC that are related to networking or webserver access. Unfortunately I can’t be of much help… we haven’t seen a problem like this in our dev instances or any others.

If there are any other clues we can help troubleshoot further.

Thanks
Ali

Hi Ali,

I did an update to the version 0.3.9 through the browser button as soon as it was released and I believe that’s when it stopped working (it might have been one update back though - 0.3.6 which I also did through the browser). I have just ran $cryosparc update from command line. See the output below where it says updated from 0.3.9 to 0.3.9. Now remote connections work fine!

$ cryosparc update

Hi @apunjani ,
I have the same problem: cryosparc starts smoothly, but web app doesn’t work.
I tried to update cryosparc as @MikeK did, but it didn’t work.

I have also tried what’s suggested in the guide here: https://blog.structura.bio/access-the-cryosparc-ui-remotely-via-ssh-tunneling/

But again it doesn’t work.

Any clue?
Thanks,

Marco
