There does not seem to be a solid solution to this.

If I am missing it please let me know. I have for the first time since I have had UE4 had this Error. “No Version information received” I have been on the Answer Hub and have not found a solution that has worked for me someone please help me solve this. I am pretty frustrated that this is not working. I have spent my summer learning how to UE4 and this is very disappointing. UE4 has worked fine until today. Do you need me to send logs or anything? Funny thing is that I have no problem connecting on my 5 year old Mac please help me and don’t say go to the Answer Hub because I have and nothing has worked. If I have missed a solution please lead me to it I hope I have overlooked it because of my frustration level.

[2014.08.28-18.13.51:778] 0]LogOnline:Warning: MCP: Client auth request failed. No response This one line from my log of the launcher when it stopped working was not in the other logs that have worked in the past. I don’t have any problems connecting to any other site that requires a log in.

UpDate: I did try one of the suggestings on the Answer Hub and that was to uninstall my current version of UE4 and to re install a clean version well that did not work very good at all. Now I cannot get to any of my projects because I no longer have an engine. What else can go wrong? Have a good day folks I am done!

wow… keep your calm and explain your problem and what you have tried slowly and clearly please

What is happening… you cant log in? you cant start the engine? you cant start your project?

Did you tried with another windows profile? did you installed a plugin?

Are you just blowing steam here or really looking for help… if it is the second one, you are clearly not doing it right

Right now I am very frustrated because I can no longer get to any of my projects here is my original post below I probably should have not posted twice about the same subject I am sorry for that but here it is.
Launcher Problem - Community & Industry Discussion - Epic Developer Community Forums!!

I have been to answer hub and there does not seem to be a definitive solution. When I uninstalled UE4 and tried to reinstall it the launcher could not connect to the internet so it did not finish installing. So now I cannot get to any of my projects. I am beginning to think it might be a problem on their end because I can connect to other sites that requires a log in and this just happened out of the blue. I am down loading the code from github and I am going to see if I can rebuild it from the source code. After that I don’t know what to do if I can’t use it why should I continue to pay. I am trying to find a solution that will work I put a lot of work into UE4 during the summer. I choose UE4 because I thought it was the best choice I think ****** because I put a lot of work into this and I don’t see a solution yet.

Well the launcher is the launcher but has little to do with your ability to launch a project.

Assuming that you no longer have a subscription this might be one of the reasons it can’t get a version number but this should not stop you from launching the project directly in the project folder.

Personally I only use the launcher to see if there is something new.

Try going directly to your project folder and launch it from there. If not then you have a problem.

Soooo

The question is do you need the launcher to work to access things like the marketplace or are you using the launcher to access your projects?

I am still active I have been subscribe since the beginning. When I uninstalled the launcher I might have messed something up.

I replied to your other thread, I hope this works for you.
