How can I make the AccuWeather widget app work again on my Samsung Galaxy Alpha?

The integrated weather widget (AccuweatherPhone2014_S_LMR_HD.apk) stopped showing up-to-date weather data on my Samsung Galaxy Alpha (SM-G850F) when I had to update it from Android 4.4.4 to 5.0.2 a while ago. I have tried deleting cache and data, but all it did is erase the cities I have saved there, and which I am not able to get back. Now it reads "Tap here to add a city" and when I do this it keeps saying "location error" or "network connexion error": I get the following error message in the LogCat: ADVHTTP IOException javaxnetsslSSLException: hostname in certificate didn't match: != OR OR OR OR OR javax.net.ssl.SSLException: hostname in certificate didn't match: != OR OR OR OR OR Note that this is the same error as when I still had the city data and tried to refresh the weather. My first step would be to at least get the cities and clock back in the widget, and then if possible resume the weather feed. My questions would be: 1. Does anyone know what is causing this error above? (Why would it expect "a248eakamainet" or a variant of it as the host name?) 2. How can I can potentially resolve it myself (e.g. by using a proxy or installing a certificate)? 3. Failing this, is there a way I can set the city myself by amending the files in there manually, such that at least the clock works (summer time icon etc.) and the city name shows? Not sure if it helps but the file structure in the widget folder is as below:

/data/data/com.sec.android.widgetapp.ap.hero.accuweather/cache/com.android.opengl.shaders_cache
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/WeatherClock
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/WeatherClock-journal
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/worldcity.db
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/worldcity.db-journal
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/files/rList-com.sec.android.widgetapp.ap.hero.accuweather.menu.MenuAdd
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/shared_prefs/config.xml
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/shared_prefs/pref_widget_count.xml

(I was able to explore the worldcity.db database using DB Browser and can see all cities data are there.) I am not a developer but have some knowledge in programming, my phone is rooted and I am somewhat familiar with running commands via ADB (I recently managed to solve a keyboard language issue myself by extracting files from a stock ROM ). My phone can access the Internet without any issues, both via WiFi and mobile data. Things I have tried so far to no avail: - Delete cache and data of the weather app. - Update the weather app (version stayed at 150901.800410 despite the "App installed" message). - Manually update the certificates in my phone by following steps described here . - Contact AccuWeather support, their reply was that "The preinstalled application on your phone was developed by a 3rd party manufacturer, with AccuWeather supplying the underlying weather data. The manufacturer is responsible for databasing, displaying, and formatting this data, as well as ensuring it is up-to-date and cached properly.". I did not contact Samsung this time as they were unable to help with the keyboard language issue I had previously. (At this point this is probably obvious, but I thought I would also mention that I am not interested in alternative weather widgets. I am also well aware that this is an old unsupported phone, but there are personal reasons why I want to make it work. I see this as a personal challenge.) Any help would be greatly appreciated!
