Hi Michon,

I believe this issue is caused by an error in the URL structure, as I noticed "////" in the link you provided.

Could you please try the following URL to see if it works for you?

Best,
Gaofei

Hello,

 

Thank you for your answer. I have been experiencing delays since the beginning of the week when making requests on cbioportal. Most of the time, I end up getting the error message that I initially sent you, sometimes it ends up working, but then I got errors when downloading .tsv mutation files (at least it seems really slow compared to the past weeks). I tried searching on cbioportal again today, adding “https://www.” at the beginning of the address, but without success. I have copied and pasted the error message I received today.

When trying the link you sent me, I get this :

 

 

Thank you for your help

 

Have a nice day
