Hello @Neurone,
as I described in #1342 the connection issue is not related to the URL. It is related to the too frequent fetching of the Address Book. If we change to this URL, soon the issue will persist. Why do we need to switch to this URL at all? We are working on changing the interval of fetching the Address Book and it will be released with the new version.
For example this issue is known also on Mainnet as well as on Testnet
