Fresh install of 0.3.17 (PC/amd64) image: no MyNode webpage served from localhost

Question

Fresh install of 0.3.17 (PC/amd64) image: no MyNode webpage served from localhost

lasermind opened this issue a year ago · 14 comments

Describe the bug
Flashed the latest PC image 0.3.17 to my system drive. Booted the system and Debian started. Logged in with "admin/bolt". Empty browser window opens with the message "This site can't be reached". No page was served.

Expected behavior
Browser window should have opened the webpage from localhost, showing the MyNode login form automatically.

Screenshots

Desktop:
Used the built-in Chromium browser of course, from 0.3.17.

MyNode hardware:

Device: Intel NUC (500GB SSD system drive, 2TB SSD data drive)
MyNode Version: 0.3.17, downloaded today and flashed freshly to the system drive

Additional context
Seems like maybe nginx is not started automatically at bootup to server the webpage. The rest of the system seems to run, as far as I can tell. Bitcoind, dockerd, containerd, tor, npm and everything is started and visible in glances. I can also login via SCP and "admin/bolt" to the machine. The machine also has internet access; I can surf to webpages normally. Only the expected MyNode page from localhost is not showing up.

What could be wrong here?

Can you try running this command and share the output?

sudo systemctl status www

Answer 2 · 2023-05-22T09:40:48.000Z

Thanks for reply! Sure, here is the output:

● www.service - myNode Web Server
   Loaded: loaded (/etc/systemd/system/www.service; enabled; vendor preset: enabled)
   Active: activating (auto-restart) (Result: exit-code) since Mon 2023-05-22 04:30:35 CDT; 7s ago
  Process: 28195 ExecStart=/usr/bin/mynode_www.sh (code=exited, status=1/FAILURE)
 Main PID: 28195 (code=exited, status=1/FAILURE)

Seems as if a service is not started.

The funny thing is: I executed sudo systemctl status www several times. When I time it correctly, for some milliseconds I get an "active" process. But then the process stops again after some more milliseconds. So it seems as if the webserver process can not be started correctly for some reason and is hung up is a re-activation loop.

It seems as if this problem is happening in all two of the new 0.3.17 images; see newest issue #789.

Answer 3 · 2023-05-23T03:27:09.000Z

Could you try this? It should show the exact reason it's failing.

sudo journalctl -u www

These are the last couple of lines, from a log already 134.000 lines long. ;) Hope it helps!

Answer 5 · 2023-05-31T05:06:23.000Z

This should be resolved a recent change. Future images should not have this issue.

#790 (comment)

Answer 6 · 2023-05-31T13:26:46.000Z

Ok, thanks! And will you make an image for a new version 0.3.18 then – hopefully also including Core 25.0 and Dojo 1.20? ;)

Answer 7 · 2023-06-06T03:12:40.000Z

Core 25.0 is planned. Dojo 1.20 may be in the next release.

Answer 8 · 2023-06-06T07:53:29.000Z

This should be resolved a recent change. Future images should not have this issue.

#790 (comment)

About this commit you mentioned: does this mean the issue is resolved in 0.3.17 also? Does this mean, I can update from an older version to 0.3.17 now and this problem does not occur any more?

Answer 9 · 2023-06-07T02:28:46.000Z

This would only effect newly created images when making one from a base image or starting from debian. It was temporarily a problem in an image I made and posted without realizing the issue, but those have been removed. New images will be made probably once v0.3.18 is out.

Answer 10 · 2023-06-08T09:03:44.000Z

In other words: when flashing the image with version 0.3.05 and then updating to the current version 0.3.17 there will not be this error? Is this correctly understood?

Answer 11 · 2023-06-09T03:56:13.000Z

Yeah, that's right @lasermind

Answer 12 · 2023-06-14T02:52:08.000Z

New images were made for v0.3.18 for the Raspi 4 and PC.

Answer 13 · 2023-06-14T08:50:14.000Z

Thanks in the name of all!

I'll try this out for PC, hopefully this week, and will also keep an eye on the issue #794 (Dojo default passwords).

Answer 14 · 2023-06-16T14:25:59.000Z

Tried the PC image for 0.3.18 and can confirm: localhost serves the MyNode GUI again.

Closing here, thanks!
