Ok so I've been having this problem for weeks now, tried searching for a solution using google, this issue has been a problem since the end of december 2020, I was unable to get the last free christmas gift because of it. 

• "We're unable to connect to the marketplace. Maybe check your internet connection?

Now i have tried every possible fix on the internet, from soft resetting my xbox, to resetting my router, nothing has worked, this also prevents me from playing in worlds with other players, or them joining mine, and this is the only game 8 have any connection issues with, I've tried using Minecraft Xbox one edition, and I can play and join games on there as well as browse the marketplace. I can also do the same with my pc version, but the xbox one bedrock (beta) has this issue. 

So any help to fix this would be great, my fixes that have failed are as follows.

• Router completely reset (and turned off while next steps were done)
• Minecraft deleted (then)
• Did a soft factory reset on my xbox. (Waited till it had finished the reset)
• Held down the xbox Button to power it down and clear the cache
• Left it over night with all power cables disconnected to xbox and router.
• Powered the router on, and reset from small reset switch at the back.
• Plugged in and powered up my Xbox once the network was back up
• Reconnected my profile to the xbox, installed minecraft.
• Switched profiles and resetting all the minecraft options in settings.
• Then ran a power cycle one more time just to be certain.

And still I have the issue, it's been weeks of trying fixes and nothing.

Sorry for the long post, I just wanted to make sure you knew what I've done to try and fix the problem before using this as my final resort, if it cant be fixed, I will just delete it from my xbox and not play it again. Thanks for any help.
