Hello @PhoneBoy thanks for the feedback, indeed sounds complicated… I will take it as a non supported feature 😞
Since this is a gateway feature, meaning that the connection initiates from the gw, I don’t think that the validation on another non-vsx gateway provides any value in relation to the reachability of the feed.
perhaps the validation is more for the content, which in any case as we talk about a dynamic list is not guaranteed to be always successful even it is validated ok for the first time. So I mean validation for the content should be there always, the initial test on a non-vsx gw does not provide any guarantee.
errors seem to appear in vsx mode correctly in the log files, so I cannot really understand the issue technically, perhaps with the exception that someone needs to dig the log files in the gw to see the error.
Obviously I just see the surface, perhaps there are other complexities under the hood but it is a pity we cannot use this feature.
