This is the problem I met when installing cryosparc2 on a computer with GPU and cuda installed correctly（but it’s not connected to the internet). So I tried to install cryosparc2_master on another CPU computer( connected to internet ) and then install cryosparc2_worker on the GPU computer. But I also met problems when connecting them.
Running into the same issue here too. I recently changed the hostname on the computer (Single installation). So, I accordingly requested the name change using the bin/cryosparcw but I kept getting errors. So, I uninstalled and reinstalled cryosparc (stopped cryosparcm, deleted master and worker, untarred, reinstalled) with the same port number and a different port number to no avail.
The database and the command core start but then the error is thrown. Specifically,
HTTPConnectionPool(host="jake, port=39102) where the actual hostname is Jake.
Using Centos 7. Tried changing the firewall settings. Same error.
Any help is appreciated! Thank you

SOLUTION
I seem to have fixed it.
This is my understanding of the issue. Please correct if you think otherwise. The reference to the hostname was being called from /etc/hosts and the hostname was listed as localhost. This should normally work but it was parsing the hostname with a lower case “jake” vs an uppercase “Jake” which is the actual hostname. When I changed the hostname in the /etc/hosts file to “Jake”, it ended up starting fine but then I could not connect using “localhost:39100” in the browser. I had to use “Jake:39100”.
To make sure, everything actually works, I uninstalled and reinstalled everything with the usual port number (39000) and it installs seamlessly.
The original post seems like a firewall issue though.
