Roblox Launch Error Macintosh

Today I tried to join a game on ROBLOX, but failed in doing so. It gave me an error along these lines

ROBLOX cannot connect to the internet

After trying other games, reinstalling, restarting wi-fi, restarting my computer, desperately searching online articles, and diving into forum threads, I still had no success. Here are my computer specs:

• MacBook Air 2012 make
• 1.4Gh Intel i5 Processor
• 4GB Random Access Memory
• OS X El Capitan
• Running Browsers:
  1. Google Chrome Version 46.0.2490.71 (64-bit)
  2. Safari Version 9.0 (11601.1.56)
  3. Mozilla Firefox Version 40.0.3
  4. Vivaldi Version 1.0.219.53 (Developer Build) (64-bit)

Is there a way to fix this? Thanks in advance.

I have had this issue before, and I have gathered a few possible answers.

1. You stated you restarted your Internet, try unplugging your router and plugging it in again. There could also be the possibility of a NAT type issue as NAT type restricts game joining and some abilities.
2. The ROBLOX connection system has had many errors, depending on how long this has been going on, you may need to contact ROBLOX support team.
3. You could try to delve deeper and ask everyone you know on and iMac (like me) if they have experienced this issue and fixed it. Personally I just waited it out and reset all my connection stuff too. May I also have the error log to check for any blatant errors and a screenshot of said error message.
