Android Question First connect to Internet Domain is very slow

[Alexander Stolte]

Hello,

i have a Domain like www.blabla.de this domain I have in the DNS settings on my VPS referenced with the ipv4 and ipv6.

On the VPS is my jRDC2, if i connect from my phone to this via ip like http://000.000.0.0:08150/therdc then i have a response time from under a second and now to my problem, if i connect via domain name (http://blabla.de:08150/therdc) the first connect lasts over 1 minute. The strange thing is, if i get the data from the first connect, the other request I get an answer in less than a second.

Why is the first request via domain so slow? Has anyone ever had this problem too?

PD: the problem occurs only on the phone, in the browser everything is fast

Is this a new domain?

the domain exists since 2 weeks.

Seems to be a problem in the wireless networks, when I switch to mobile data, then I have no waiting time in the first request.
