Error Message

Does anybody know what this message means?
Error: Http error 503 while requesting https://ig0.herokuapp.com/getgame?site=littlegolem&id=2268845

I got when I tried to access igo link....

I got the same message. Seams to be a change/bug in the transfer Protokoll.
The question is on wich side.

Seems to be a problem with the ig0.herokuapp.com site; I get the error that according to herokuapp.com, LF has an expired certificate and then it cannot be (safely) accessed; but does not seen actually true, as my Firefox would certainly scream in horror when accessing LG through https with an expired certificate, but it doesn't and, in fact, it reports LG certificate will expire on 2021-12-18.

So, it seem something does not 'close the circle' at herokuapp.com. Sorry, I cannot go further than that.

It's a shame because ig0 is much better than EidoGo....

I can't use either now. iGo hasn't worked for months and now EidoGo won't, either. They don't like LG's data format.

In case of ig0 it worked to download the SGF file and then upload it in ig0.

@Crelo: Thanks for the hint.

Igo returns: littlegolem unavailable: certificate has expired
