SSH access stopped working after firmware upgrade

[Hvmhvm 0]

After updating the firmware to version 5.2.16.20200331 the ssh access in developer mode stopped working on my Ultimaker 3.

Have you already tried to disable the developer mode and enabled it again?

Yes, but that didn’t change anything 😞

I’m guessing it may have to do with the fact I am using 3dprinteros, which allows me to use my UM3 from an iPad. Is there a way to go back to the previous firmware version (where everything was still working perfectly)?

I think reverting to the previous version should work. Just download the firmware from the UM website, copy it to a USB stick and do the downgrade from the stick. Not 100% if it really works or if there is a check which prevents you from downgrading, but I think it should work.

Unfortunately it seems that the only downloadable versions are the latest and a really old version 4.3.97, or am I missing something?

In the end I found that by replacing the link to the latest release with the numbers of the previous (which I found in an email on this forum) I could download the previous version from:

http://software.ultimaker.com/releases/firmware/9511/stable/5.2.11.20190503/um-update-5.2.11.20190503.swu

 

The downgrade worked perfectly, and now I have ssh access again in the developer mode, and I can use 3dprinteros again to print from my iPad! 😀

Great and I am glad that you were able to fix it.
