We created a contest in gyms, and trying to upload problems to it, but it seems that the ftp server is not responding.

→ External storage error The external storage was offline or malfunctioned during the last contest update. Please wait for some time, then go to the contest edit page and click "Save changes" to synchronize data.

After click "Save changes", it prompted: "Can't create or update contest in the external storage"

We tried to connect to the ftp server, but failed. It seems that the ftp server is not working.

MikeMirzayanov can you take a look? We are planning to use the contest this weekend. Thank you.

Upd We upload the problems in "Add problems from contest", it works.
