Hi @robert75barta I was in the same position until Friday. I am new to iHost and my device came with 1.6.3 too more like you experiencing same issues. I did time out error and not able to list any docker images or install what was listed. I did raise ticket and they looked at logs and told me I had time errors.
In the end I installed wireshark on local PC and found my ihost was blocked both way by IPS on my Unifi UDM Router. I have allow this then I was able to link as well update. Now I am on 1.13.2 Also have the option to check for update next the version on iHost settings Page. Hope this helps. Check your Router fire wall rules and if needed add the iHost to allowed list.
