Can't sync on phone nor on laptops

[Qazi]

I have a Surge which I bought early March this year (through eBay, in almost new condition). I have a Samsung S6 which I use for syncing the Surge. The Surge had been syncing with the Android app very well till the 6th of April and now it just won't sync anymore.
I have a MacBook Pro and Samsung laptop but have never been able to sync the Surge on them (from day one, I get the error of "No Internet connection found. Please check your Internet connection." on the Fitbit Connect, even on being connected to the Internet all the time). I have connected the Bluetooth dongle, uninstalled, re-downloaded and re-installed the Fitbit Connect apps on MacBook and the PC laptop several times but just cannot get the Fitbit Connect working and syncing with my Surge.

Now since the last week or so, I have been having syncing issues with my phone too. My last sync with the Surge was on 6th April and since then even on trying a dozen times on daily basis, the Surge won't sync with the S6 app anymore. Often it shows the current day stats on the S6 app but it just doesn't store it in the history (as in the stats of the day being part of the previous history. The stats are stuck till the 6th April.). I have uninstalled, re-downloaded, re-installed the Android app; have shutdown the Surge, restarted it; made sure the Bluetooth connection between the phone and the Surge is correct; but nothing works. The daily stats just don't get stored and next day I see empty stats on the app.

Can anyone here please guide me what I could do to sort this out. Have to mention again that till 6th April, the Surge would sync with the phone perfectly and I would get to see the stats of previous days and weeks the next day.

I would appreciate if I could be advised any troubleshooting for both issues - the non-syncing with the phone and the laptops - apart from the already done troubleshooting which I have mentioned above. I'd really appreciate any help since I'm thinking of getting rid of the Surge if it doesn't work out correctly anymore.

Thanks and regards,
Qazi

Hello @Qazi, welcome to our community my friend. Certainly this is a big issue your tracker is not syncing with any of your devices. 

Regard the Internet connection error you are getting, can be several reasons:

1. You are running the latest version of Fitbit Connect. You can find the latest version at fitbit.com/setup Before reinstalling the software, please disable any anti-virus programs to reduce installation complications. You can re-enable your anti-virus once Fitbit Connect is installed. 
2. Fitbit Connect is included in your firewall's list of allowed programs. For instructions, see: http://windows.microsoft.com/en-US/windows7/Allow-a-program-to-communicate-through-Windows-Firewall 
3. You have re-entered any proxy settings that may have been reset after installation (see imgur.com/a/yCfro for instructions). 

If you need to manually configure port access for your computer, Fitbit Connect requires access to ports 80 and 443 to communicate with Fitbit.com servers. 

About your phone, I recommend the following post from one of my community's friend. He shared the troubleshooting steps for this type of issues and it may come handy to resolved the problem. Please go here for more information.

Hope all this information helps and hope to see you around.
