Error upgrading from 3.4.8 to 3.5.0

[homeopatix]

Hello, after i upgraded my netbox-docker version from 3.4.8 to 3.5.0 i have this error

Server Error
There was a problem with your request. Please contact an administrator.

The complete exception is provided below:

<class 'http.client.RemoteDisconnected'>

Remote end closed connection without response

Python version: 3.10.6
NetBox version: 3.5.0

and impossible to connect to my nextbox anymore

[homeopatix]

I did a small try, downgrading back to version 3.4.8 and everything is working fine again, so i would really know from where the probleme is comming from, any ideas ? any one ?

Thanks in advance for your help

[homeopatix]

I could upgrade to the 3.4.9 with no probleme, but i can not upgrade to the 3.5.0

Please can you provide a full backtrace: set ADMINS and EMAIL in configuration.py, and/or set DEBUG=True.

Given that this is a HTTP client request, I wondered if perhaps you were caught by new census feature in 3.4.9:

#12337 - Enable anonymized reporting of census data

However, since you say 3.4.9 works, that's probably not it - unless there's an intermittent problem with connectivity to the census server. A backtrace will make it clear one way or the other; and/or you could try setting CENSUS_REPORTING_ENABLED=False

[homeopatix]

Hello, thank you for your response, i tried to set
CENSUS_REPORTING_ENABLED=False

but that does not change, the probleme is still there, i provide you my full backtrace as asked
please let me know if i can do something more the help you find out this probleme
to precise something i am running this netbox docker in a Stack with portainer

In v3.5.0, a new configurable dashboard with widgets was introduced. It looks like one of the default widgets tries to make Internet connections, and is raising exceptions for you. I see that your traceback is within RSSFeedWidget:

File "/opt/netbox/netbox/extras/dashboard/widgets.py", line 272, in render
feed = self.get_feed()

There is a similar problem at #12384 and #12421. v3.5.1 will include a fix with a 3-second timeout, and it looks like it also catches requests.exceptions.RequestException; however this might not fix it for you since I don't know if the exception you see (RemoteDisconnected) is a subclass of RequestException. I think OSError and RuntimeError should be caught.

There is a suggested solution here to change your DEFAULT_DASHBOARD setting (however I don't have a v3.5 instance here to test with).

[homeopatix]

thank you very much for your answer, my server (that hold the netbox docker) as no connection over the internet, it is probably that
thank you again for your time, and i will be waiting for the 3.5.1 to suppress this error

[homeopatix]

I did a lot of new test, there are my results...

I tried this #12384 but that does not solve the probleme it makes an error still in the rss.feed even if i am not using it in the
dault dashboard configuration

I tried to create a fresh new installation of netbox into my portainer using a stack with a docker-compose file
every thing is created correctly, i just have to recreate/duplicate the container to give him a new port and every thing is running, but when i want to connect to it, it display the same error as before with the render_widget command in the widget.html file, so the probleme
is not comming for old datas saved in local volumes

if i comment the line 34 in the widget.html file like this {#% render_widget widget %#} and then recreate the whole stack everything is working fine, netbox open up and display a screen with the new interface of the 3.5.0 with all the widgets empty, but all my datas are there

So for me, i think, but i am not sur at all, the probleme is not comming from an internet connection, but really comming from the new dasboard of the 3.5.0 when netbox is trying to render the widgets

[candlerb]

Unless you want to mess around with changing the default dashboard in extra.py, I'd suggest that you'd be better off deploying Netbox v3.4.10 for now, and then upgrade to v3.5.1 when it comes out.

[homeopatix]

That is what i did, thank for your support

[homeopatix]

Upgraded to V3.5.1 and every things is working fine now
