Why were the octopus rates not available?

[paulgee31]

I’m hazarding a guess it was a web server issues at the octopus end.

[springfall2008]

I've released a fix for the bad gateway one.

For the joining saving sessions, it should only try to join if you haven't joined already, did this error continue?

[paulgee31]

I’ve seem it happen twice over two saving sessions.

Predbat joins the saving sessions, then attempts to join a second time but them stops after that. Any chance it could be a timing or caching issues where the second time it is getting old data.

[springfall2008]

Yes could be, I put a fix in the latest version to re-fetch the saving sessions after the join so would be interested to see if that solves it.
