I have just checked it now and as far as I can see it is working. Can you please provide the exact URL and/or steps you have taken when you encountered the error?

srobb1 commented 3 years ago

Here is the URL I am using on my Mac in chrome https://www.ebi.ac.uk/ols/ontologies/plana/terms?iri=http%3A%2F%2Fpurl.obolibrary.org%2Fobo%2FPLANA_0000418. Also two of my colleagues are having the same issue with the depiction. Two of us are on macs the other on windows. But!!!! it does work on my phone! What the heck?!

srobb1 commented 3 years ago

It works on Safari. Not Chrome.

henrietteharmse commented 3 years ago

Thanks for pointing that out. So checking this again I can confirm it working in Firefox as well, but not in Chrome. We try to figure out why on earth it is not working Chrome.

Can you by any chance confirm which browsers your colleagues were using when this did not work for them?

jamesamcl commented 3 years ago

The problem is that:

  1. The URL in the depiction property is http://purl.obolibrary.org/obo/plana/images/head.png
  2. Chrome's security policy enforces https because OLS is accessed over HTTPS. So, https://purl.obolibrary.org/obo/plana/images/head.png is requested instead.
  3. Requests to https://purl.obolibrary.org/obo/plana/images/head.png time out. Try for example curl https://purl.obolibrary.org/obo/plana/images/head.png: curl: (7) Failed to connect to purl.obolibrary.org port 443: Operation timed out

So there is a general problem with https access to https://purl.obolibrary.org/ which is not an issue with OLS. Not sure who to contact about this?

Ok I checked with OBO foundry and @jamesaoverton and the OBO purl system does not currently support https. @srobb1 you will have to code the links to the images using the github https URLs unfortunately! There is nothing that can be done on the OLS side. You could make a ticket here:

https://github.com/OBOFoundry/purl.obolibrary.org/issues

And ask for HTTPS support!

srobb1 commented 3 years ago

Thank you. I have my depiction pointing to raw github links. This is working now. I created an issue on purl.obolibrary to see if they will consider supporting https.

Thank you for everyone's help to figure this out. Sofia
