When trying to complete the last two colour challenges. It says "Network Error Unable to join event. Please try again later"
I am using PC.
I should be able to complete, I have tried multiple times and multiple days. But not working while the other 3 colours did.

I have the same problem. Did the first 4 levels of each color just fine and cannot get into the 5th on any color! Please help!!

Hello, I have a problem with the color challenge I can not finish it, when clicking on the last battle, "Network error" comes out

Cannot complete the color challenge for the game need help

How do I get this error fixed I am having the same issue ? Seems to do it on the last colour challenge with Swamps for me ????

All I have left on all the color challenges is the pvp and it won't let me due to the "network error". I have read everything here and it all says to report the issue and ask for manual completion and the decks that are rewarded for completion

I need help please

Color challenge incompletable due to network error.

I really can't do anything

How many years is it going to take them to fix this issue?

I finally got to the last battle of the color challenge and have come face to face with my greatest foe on this game yet: a network error bug that does not allow me to even play the game.

Same. They completed it manually for me, but it's glitched: I didn't get the rewards associated with completing them.

Grif's advice worked.

Not sure it helps, but when I check the deck that I'm supposed to play with, I don't have any of the cards of the Standard set.
Maybe the bug is somewhere when we are supposedly given the cards from the challenge?

I can't access the last match of each colour of the Colour challenge. How can I fix it? Can you help me, thanks.
