There are two protocols (crudely) for carrying webpage type data, http and https (the latter having better security). The Naim kit sends its login using http, Tidal put in a change that redirected it to their https software. That is visible to the card in the Naim, and sensibly it doesn’t trust a login that has been redirected elsewhere, so doesn’t continue with the credentials.
(Non-techie version I hope, but that always runs the risk of still being over-technical while offending the sensibilities of experts. My excuse is that I retired nearly a year ago after 35 years in networking and systems, so you can’t expect me to still remember.)
Same here in Sowerby Bridge Dave, glad you’re well, we’ll have to have a cuppa and cake with some music when the situation allows (or a glass of wine).
Lucky I got it right, I should know a bit about this stuff, years ago I worked in a network security team for a big U.K. telco with a chap called Peter Harris. You might know his nephew Steve…
