Issues with new 5.3.0 firmware

[Deb 0]

Hi.. we have updated Ultimaker 3 with firmware 5.3.0 but after installation the printer kept showing that the firmware still needs updating- it kept doing this on a loop. Also after the update the printer lost connection over the network.  Sometimes it's connected for a few seconds and then it loses connection. CURA version is 4.11.0.  Anyone experiencing this please? And any tips? Thanks

Regard the update loop, here is an explanation, but you can just ignore it:

 

I think any other issues you see with 5.3.0 are not related to the firmware, because the only change in 5.3.0 is that UM has renewed the root ca certificates for the digital factory connection.

Yes but well, not exactly...

For the UM3 specifically we did have to change a lot, we're not sure why, but we had to enable TLSv1.3 to get it to work with the new certificate, previously TLSv1.2 was fine, to do that we had to update python, libssl and all it's dependencies including the indirect dependency that is nginx (the web-server on the printer) .

So there are quite a few changes, though none "should" have influence on printing and the printer applications.

We did have to update some standard packages to get the WiFi working correctly, though I haven't seen or heard about any problems like this. If you are on WiFi, can you check if you experience the same problems when connecting trough Ethernet (wired cable).

Thanks für the clarification, I am not a full time python developer, but I do a lot of python in our company, so I can imagine that it was a hard weekend for all of you guys.

 

So thanks for your work to bring a fix for the SSL issue so fast!

I also encountered the Wi-Fi connection issue with 5.3.0. Now I have to use USB stick to transfer the print.
