237-3ubuntu10.2 fixed the issue for me in Bionic. With this version installed I was able to successfully log into the wifi on the train in the Netherlands. Previously I could not load the accept page.

[Test Case] * systemd-resolved something-nonexistant.ubuntu.com * monitor the logs, and check that the transaction has been downgraded multiple times and tried at least once at a feature level below D0. There should be a downgrade message in the log. * Note, it will be cached, thus one may need to call $ systemd-resolved --flush-caches [Regression Potential] * Legitimate NXDOMAIN queries will now take longer, as they will be retried multiple times with different features sets until an answer is found. At that point the query will be cached and will return quickly. This is needed to work-around bad captive portals that do not support dns queries with D0. Post-captive portal, the feature level can usually be cranked back up and it does after a grace period. [Other Info] * Original bug report I was asked to create a new bug for this in https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1727237 as it seems to be a different issue. I have installed the nightly image of Kubuntu Bionic from 25th of April. There systemd is in version 237-3ubuntu10. When connecting to the wifi hotspot in my hotel (Quality Hotel Augsburg) I cannot open the hotspot landing page that should give me access to the WIFI. With Windows and on an Iphone it's working. For the following distributions I can confirm it not working: Kubuntu 17.10 Kubuntu 18.04 (nightly image 25th of April 2018) The logs were taken on 18.04. Workaround: sudo systemctl disable systemd-resolved.service sudo service systemd-resolved stop sudo rm /etc/resolv.conf sudo nano /etc/NetworkManager/NetworkManager.conf >> add "dns=default" under [main] sudo service network-manager restart Then I can connect to the WIFI and I see the login page in Firefox. To capture some data I did the following: - connect to Hotspot - enter golem.de Case 1: Fresh default Kubuntu install With a default Kubuntu install it does not work. I can connect to the WIFI and get IP and DNS from DHCP but I cannot resolve any hostname. When trying to open the router ip directly in the browser it forwards to hotsplots.de which cannot be resolved. Case 2: With aforementioned Workaround I connect to the wifi, I open firefox and the login page shows up (if I havent been connected yet. In the capture I already was able to connect to the hotspot which allows immediately to connect to the webpage) PS: I'll be in this hotel till Friday 27th if more information are required.
