Just three days ago, it still was able to give me OD readings. I have been rebooting my Pioreactor. I also tried to update the software, but it encountered errors as well:
Hm, are you Pioreactor(s) connected to the internet? If not, this would prevent the Pioreactor from updating using the UI. There are other ways to update: Updating the Pioreactor software | Pioreactor Docs
For your “lost” message: are you seeing this consistently? Is it only the od reading job that suffers this problem?
