I've found that on many public wifi services that redirect you to a browser login page, email won't update ("problem with sync") and other apps cannot connect to the internet, even though the browser works fine.

How can I diagnose why the apps won't connect? (For example, how do I check if any ports are being blocked? How can I see whether connman thinks there is a connection?)
Are there any known issues with this?
Most importantly, are there any workarounds to get my email to update using public wifi? (Are there any settings I can play with changing? Have you had any luck with reconnection tricks like @r0kk3rz mentioned?)

Edit: XperiaX: (Public Hotspots) It seems the problem with not apering sign in browserpage is present again. I tried it on a trainstation (T-Mobile Germany Hotspot) and other providers. On the XperiaX with android it worked well. After flashing SailfishX (official) [2.1.3.5 Kymijoki] it is not working. Please check that again! and reopen this question.

Are those WiFis actually public? What's the purpose of those login pages?

Many hotel and shop wifi services use this system of taking you to a browser login page. Some of these ask for payment too, but that isn't the issue here. Once the browser has unrestricted internet access, other apps should get it too.

Often such hotel wifis are severely limited even after a successful login. Only a few ports to which outbound connections are allowed to. If connections to e.g. IMAPS port are blocked, there is absolutely nothing Jolla can do about it.

this has been happening to me too. particularly in Germany.

the issue isnt blocked ports but connman thinking there is no internet connection, and many apps are set to not bother trying if connman reports no connection.

If after authenticating I drop the connection and reconnect, everything works fine, but only if the wifi resumes the session

had that problem too in greece with a hotels wifi

sometimes it helped to quickly disconnect and reconnect again. So i was still logged in and a popup appeared showing a working wlan connection

sometimes the system ui asked for account details, in this case i had no problems

The device will have do recheck for the connectivity after succesful hotspot login as the connection is ready-state (browser is an exception which works on ready-state) and not online-state.

However, this is going to change in update 10 and other apps will be allowed to use network as well when the connection is on ready-state.

I suffered just the same problem before but now I can confirm it's not reproducible anymore on version 1.0.8.21. Thanks for the fix, guys! It was especially important for me as the whole Wi-Fi network in Moscow subway uses this scheme of redirect. Now everything works just fine.

@aclex Which fix? The one coming in update 10?

Sthocs ( 2014-10-15 01:08:20 +0300 )edit

@Sthocs I found it working after recent minor security update to Tahkalampi (as I mentioned, version 1.0.8.21). To my harm, I wasn't too familiar with the roadmap so thought that it was update 10, sorry. Anyway, I still can confirm that it works for me now.

aclex ( 2014-10-15 01:51:48 +0300 )edit

@aclex ok, actually update 10 is the one that will come after the one we are waiting for (it will probably be version 1.0.10.x). Normally, 1.0.8.21 wasn't containing any anything but bash security patches. Maybe your phone got used to the network =P

Sthocs ( 2014-10-15 13:19:55 +0300 )edit

@Sthocs yes, it's strange then.. Perhaps, something was changed in the network infrastructure at the same time of 1.0.8.21 release, so that's that I mixed it up. Anyway, I'm so sorry for disturbing, too much wanted to share good news :) Sorry.

Hi, I had this issue this week-end so I've dug into the WLAN menu, and I've been able to make the whole phone connect, by simply long-pressing the wifi name and hitting "Edit". It probably made the phone check again the connection and so the little exclamation mark disappeared and all the apps got access to Internet.

Hope it works for you! (if it doesn't, also try to untick/tick the "Auto-retrieve IP address" option also).
