HttpComponents connection error response code 500

Hello,
Last day i tried to add dl4j extension by drag and drop from Knime hub. But https://hub.knime.com/knime/extensions/org.knime.features.ext.textprocessing.dl4j/latest/content.xml is in error.
Since then, my Knime analytics version (4.7) as a persistent error (see capture when i open Knime or when i tried to instal new extensions). How can i fix it ?
Best regards,

Joël

Hi @JPollet ,
thank you your question. I will ask internally and we will get back to you.

Thank you @darspir,
By the way if I try to install new extension, Knime have some problems :


But I can bypass theses messages. It sounds like the initial testing with a wrong adress is still in memory some where.

Hi @JPollet ,
it looks like that the link KNIME shows (https://hub.knime.com/knime/extensions/org.knime.features.ext.textprocessing.dl4j/latest/content.xml) is not an update cite and, actually, does not exist at all. We do not know how exactly it occurred in the update cites but it did. As long as it is there, this error will remain.

Could you please check the Avaliable Software Sites:
File → Preferences → Install/Updated → Avaliable Software Sites

If the link we talk about is there, please, remove it.

Let me know if it helps!
Best,
Daria

It seems to be fine and solved the problem (and I should have thought about it !!).
Thanks @daspir !
