Hello.
Could not find any appropriate contacts for tech support, so trying to contact to Abvent with that forum.
Please pay your attention to situation with artlantis.com availability for Russian customers. They cannot get access to
eais.rkn.gov.ru/ .Right now it is not listed but three days ago Iip was in block list.
I would also reccommend you to check your SSL certificate on activation.artlantis.com/ it seems to be expired on 20 aug 2018.
