Unable to launch binder repos

Sorry in advance if this is not the correct forum - I couldn’t work out the right place to post this issue.

I seem to be unable to launch any binder repos at the moment. This includes all the examples repositories I’ve tried in the Binder documentation under “Reference”/“Example repositories” (Apologies, as a new discourse user I’m only allowed to post two links, which I’ve use up below)

I seem to get a range of errors, but in most cases the error is one of either:

Launch attempt 1 failed, retrying...
Launch attempt 2 failed, retrying...
Launch attempt 3 failed, retrying...
Failed to launch image

(e.g. this binder link from the docs)


Container engine initialization error: ('Check if docker is running on the host.', DockerException("Error while fetching server API version: ('Connection aborted.', ConnectionRefusedError(111, 'Connection refused'))"))

(e.g. this binder link from the docs)

(Note, it also looks like a number of the links in the documentation need to have their git ref updated from master to main, but I think that’s a separate issue)

Please see the blog post about reduced MyBinder capacity.


Thanks @bollwyvl for the quick response. And apologies - I’d missed that blog post


After “Pushing image” I get the error:

“unauthorized: pq: remaining connection slots are reserved for non-replication superuser connections”

Is this due to the same reason, i.e., reduced capacity?
