"The CodaLab site is currently unavailable"

[jmlipman]

Hi,

I'm trying to download a dataset from a competition, but the website keeps loading and throws me the following error: "The CodaLab site is currently unavailable". This error happens when I access the URL https://competitions.codalab.org/competitions/18467 and when I'm logged in. On the contrary, if I'm logged out, this error doesn't show up, but then I cannot download the dataset.

Thanks!

Hi @jmlipman,

I am not able to reproduce this problem. I am able to access https://competitions.codalab.org/competitions/18467 either being logged in or not.

Could you try again, and share more information about how this problem happens?

[jmlipman]

Hi,

I've simply tried to access in Chrome and Firefox and I still get the same error:

In both cases (Chrome and Firefox), if I access in a private tab (i.e., not logged in), it works.

Depending on what account I'm logged in, I am now able to reproduce the bug.

Can you please share your username?

In the meantime, you can try to contact the organizers in order to get the link to the dataset.

Whenever I try to load the page being logged as a participant accepted in the competition, I get the error mentioned above: "The CodaLab site is currently unavailable".

In the logs I found the following error message.

@ObadaS It looks like the DNS problem we solved on Codabench and on CodaLab servers is somehow happening also on the old production server competitions.codalab.org. Any clue?
