SSH and VNC connections work, but not HTTP

[justgettingby]

Hi,
I have been using weaved for a few weeks now, and all went smoothly until recently when my HTTP connections stopped working.

I am running a RPi3 with SSH and VNC services, no problems. But since this weekend, the HTTP service has returned "No connected service found".

I know the application is working because I can connect locally (using IP address in browser), but the connection through weaved is failing. I have tried uninstalling and reinstalling the service, and read through the FAQs. I am trying to connect on port 8765

sudo netstat -apn | grep tcp | grep LISTEN
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 878/Xtightvnc
tcp 0 0 0.0.0.0:8081 0.0.0.0:* LISTEN 1118/motion
tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 878/Xtightvnc
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 552/sshd
tcp 0 0 0.0.0.0:8765 0.0.0.0:* LISTEN 454/python
tcp 0 0 127.0.0.1:7999 0.0.0.0:* LISTEN 1118/motion
tcp6 0 0 :::22 :::* LISTEN 552/sshd

Sometimes, a program is written such that it will accept IP traffic from a specific interface, such as the ethernet or wi-fi interface, but not others. Traffic that comes through the remot3.it daemon will appear to be coming from the localhost address, which is 127.0.0.1. Check your Python program for any limitations of this kind.

I have two RPi's registered - RPi1 & RPi3 & both are giving the same error on HTTP: "No Connected Service Found". I was able to connect about 8 hours ago but no longer. Please advise. Thanks.

This means that the remot3.it daemon cannot find an active tcp listener at the configured port. I suggest that, assuming you have an SSH connection, you get a console and run:

sudo netstat -apn | grep tcp | grep LISTEN

If you have (for example) apache2 configured to listen on port 80, you'll see an entry like this:

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 2132/apache2

If the services were working before and have stopped running, then you'll need to figure out why that happened.

The RPi1 is working again without doing anything - it hasn't even been rebooted. The RPi3 is however still not accessible via HTTP remotely.

Here is the output of the command on the RPi3:

sudo netstat -apn | grep tcp | grep LISTEN
tcp 0 0 0.0.0.0:6789 0.0.0.0:* LISTEN 632/nzbget
tcp 0 0 0.0.0.0:5801 0.0.0.0:* LISTEN 512/vncserver-x11-c
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 512/vncserver-x11-c
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 516/sshd
tcp6 0 0 :::5801 :::* LISTEN 512/vncserver-x11-c
tcp6 0 0 :::5901 :::* LISTEN 512/vncserver-x11-c
tcp6 0 0 :::22 :::* LISTEN 516/sshd

HTTP is configured for nzbget on port 6789. I'm able to access it via the LAN but no longer through remote3.it or Weaved. The other two: sshd, port 22 & vncserver, port 4901 are accessible. Nothing has changed. Each is setup in a different location/internet connection. They just stopped working via HTTP like justgettingby reported above. The problem seems to be on your side.

Update from my side:
I had the same issue, where nothing had changed on my RPi3 (or RPi Zero which was also affected). It just stopped working over the weekend, and couldn't access it at all yesterday.

However, it seems to be working again this morning with no changes (apart from having taken my laptop home last night, then bringing it back to my office today). I'm now able to log into both HTTP sessions on those devices.

I also have a third RPi3 at a completely different site, which I attempted to connect to this morning, but got the same "No Connected Service Found" message. I logged out/in of the remot3.it account, and that started working again. Not sure if related.

Please copy/paste the URL from a failing connection and e-mail it to support@remot3.it. We may be having an issue with one of our proxy servers.

My RPi3 is now working again. I'll definitely email support@remot3.it if the issue reoccurs.

Thanks for letting us know about it, we fixed it. Sorry about the hassle.
