    Hi Everyone

    I am having this annoying problem going on with my G4 (H815T). I am using 1GB mobile data on a du SIM, all applications and web browsing work except facebook. The facebook application only seems to work on wifi and it will not connect if mobile data is on (regardless of 2G 3G 4G). I put the SIM on my older G2 phone to check whether its carrier related but it works perfectly there. Its only seldom when it works just for a bit then it wont.

    Things tried:
    - Uninstalling reinstalling app
    - Updating app and phone
    - Clearing data, cache, system cache
    - Switching off phone, removing SIM and battery for 30 seconds and then reinserting
    - Virus check

    If I am logged in, it will not work, and if I am not logged in, I get this error written when I try to login:

    "Sorry, unable to login to Facebook. Please check your network connection or try again later. (HttpNetworkException: proxy HTTP status 400)"

    Any help please?

    Having the same problem, Galaxy S4 on Straight Talk here. Problem started about a day ago. I'm guessing this is a glitch with the app itself lol. Hopefully they will fix it soon.

    Hi all there!
    Technically, 400 status code is Bad Request response from server so most likely problem is on Facebook server.
    But in any case - did you checked if internet is working on your devices at all? E.g. if google.com is loding correctly in browser etc.?

    everything works fine (just that app doesn't). So i can surf through browser chrome or internet, each site opened normally fast on mobile data, beside this app. I can also use other apps and work great, but this one...
    Tried to remove completely facebook app and facebook messenger app (i think the other one is unnecessery, if i wrote it well), but when instal it again, that **** still happens.

    Okay guys so after really intense searching and implementing different trials, i found a solution which worked for me, I hope this would help all of you.
    So you go into mobile data, then APN settings. Go into both the WAP and Internet APNs, and I noticed that there was a proxy and port set. I cleared both of them, and wola! it works!

    I dont know whether it relates to the error shown by the facebook app upon login, but the error did mention the word "proxy" so I tried that out and worked. Clearing the proxy did not affect anything else, neither connections nor speed for other apps or browsing

    Do try it out and check if it works!

    I tried that, but on my lg g3 i dont have settings as you called above, just apn settings automaticaly set from my network operator. I cant delete theme (or clear), but you were right, they are set to some port. I did the acces point reset to default, but still cant login to facebook app anybody else tried this method? Thanks anyway for giving a shot..

    Just perfect! Thanks for your help.

    After I deleted the proxy and proxyport in the APN settings, the Facebook app can connect again via mobile data. My phone: SONY Xperia Z3 compact, Android 5.1.1, FB App

    I have the same problem. I use straight talk with a AT&T phone. So I have specific settings for my data to work. If I change the ports and proxy nothing works. It worked fine until a few days ago. It's really annoying.

    Mobile Networks
    Access Point Names

    then select internet

    then delete APN

    restart Phone

    then request APN Settings from the service provider

    Install the settings

    restart the phone again

    this worked for me. try your luck

    Did you try to use Facebook without application? Just through your browser? Is it working normally?

    i use net10 and all i did was delete the proxy settings as the user above advised and it worked. Just go to your APN settings and delete the proxy server and proxy port number and it works like a charm. nothing else on my phone was affected by doing this. thanks for the help guys.

    Maybe this sounds stupid, but i dont have an option to delete the proxy server. I found everything like you said in APN settings, but dont know how to delete it or unable it, whatever. I contacted my provider, waiting for an answer. Maybe someone with lg g3 or g4 knows what i am talking about.

    Pozdrav druze.. Nemam LG, nego Samsung, ali dosta ljudi iz mog okruzenja je odradilo to na njihovim telefonima koji su razni.. Ako ne mozes da ga izbrises, ti izbrisi sve APN-ove i napravi nov, ali da se podudara sa trenutnim:
    APN - Access Point Name: - [isto stavljas kao sto je trenutno]
    Login - Username: - [isto stavljas kao sto je trenutno]
    Password: [isto stavljas kao sto je trenutno]
    Proxy: [ostavljas prazno]
    MCC: [isto stavljas kao sto je trenutno]
    MNC: [isto stavljas kao sto je trenutno]

    Nadam se da ce tako uspeti. Pozdrav i javi sta si uradio..

    Here is on English for all who have LG G-series.
    Try deleting all APNs, create a single APN to match the correct settings without the proxy.

    Internet Setting:-
    APN - Access Point Name: [same as now]
    Login - Username: [same as now]
    Password: [same as now]
    Proxy: [leave blank]
    MCC: [same as now]
    MNC: [same as now]

    Do you happen to have a Samsung Galaxy S5 Active? Because I am in the same situation and I was wondering if you were able to fix this issue?!
