    I had no problem in using/downloading FB messenger on my Huawei SCL-L01 untill a couple of months ago.
    Then I had to uninstall and install the app again but since then I cant do that.
    I follow the t/s steps as advised bu still get the error 504.
    Thank you.

    I may have a solution, go to google.com type in messenger apk. Choose a site, my favorite website is apkmirror.com scroll down a little and it will tell you if it is the latest update if it is, download it. if not scroll down a little more and you will see all versions of messenger. Next before you open download you must go to your settings open security and check the box next to unknown sources download should be done by now so scroll down from top of phone and click on download and finish if an error occurred try going to file manager find the download folder and click on download again... let me know if this helped
