I am experiencing this problem in 2018. Did anybody encounter and or fix it in the meantime?
If so your advice would be greatly appreciated. I am normally able to call remote endpoints using ARC2.
I run the script on my external host. It works fine for many known endpoints. It seems not to work fine for the endpoint I have at work which ends in 8090. Is the port an issue perhaps?
A first wild guess is, that the deployed server has some kind of a blacklist of ports active. Can you check that?
Do you have shell access to the deployed server? If so, can you ping the remote endpoint using curl, for instance?
Any news here?
Close because no feedback.
When I do request from my development machine to my remote endpoint, all is OK When I do the same request from deployed server to my remote endpoint, I get the following message Query errorsArray ( [0] => Socket error: Could not connect to "http://137.194.54.188:8890/sparql?query=%0A%0APREFIX+rdf%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22-rdf-syntax-ns%23%3E%0APREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0APREFIX+owl%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2002%2F07%2Fowl%23%3E%0Aselect+distinct+%3Fp+%3Fo+where+%7B%0AGRAPH+%3Chttp%3A%2F%2Fgivingsense.eu%2Ffrscol%2FFrSchoolSystem%2F%3E+%7B%0A%3Chttp%3A%2F%2Fgivingsense.eu%2Ffrscol%2FFrSchoolSystem%2FPeriod1%3E+%3Fp+%3Fo+.%0A%7D%0A%7D%0A++" (proxy: 0): Connexion terminée par expiration du délai d'attente in ARC2_Reader [1] => missing stream in "getFormat" via ARC2_Reader [2] => missing stream in "readStream" http://137.194.54.188:8890/sparql?query=%0A%0APREFIX+rdf%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22-rdf-syntax-ns%23%3E%0APREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0APREFIX+owl%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2002%2F07%2Fowl%23%3E%0Aselect+distinct+%3Fp+%3Fo+where+%7B%0AGRAPH+%3Chttp%3A%2F%2Fgivingsense.eu%2Ffrscol%2FFrSchoolSystem%2F%3E+%7B%0A%3Chttp%3A%2F%2Fgivingsense.eu%2Ffrscol%2FFrSchoolSystem%2FPeriod1%3E+%3Fp+%3Fo+.%0A%7D%0A%7D%0A++ via ARC2_Reader )
