Windows .exe IOException on Login Attempt

[ManaaniWanderer]

I have the latest version of the launcher from the site, but when I go to login it Gives an IOException Error.

What I've tried so far:

• Win 7 Compatabilty Mode
• Running as an Adminstrator
• Copying Password from text file to both FTB and Vanilla launchers to confirm it works, and Vanilla worked fine
• Reinstalling Java

Paste bin is here, or if you prefer: http://pastebin.com/F1iX5Dni

Managed to find a workaround to connect successfully, info on the second page.

Delete the profile and make a new one in the launcher

 

[ManaaniWanderer]

Just tried it, and nothing changed I still get the IOException with no reason why login failed.

 

[Ashzification]

Try changing your password

No dice, still getting IOException, link is the extended pastebin log from this attempt http://pastebin.com/ehJu0WhN

Well, then you get the same thing I tell everyone else, but this time for a different reason (usually I post it because people don't give enough or the right information, or what they have given isn't done right)

To confirm: this is a premium minecraft/mojang account, right?

 

[ManaaniWanderer]

It is,yes.

edit:Texture packs and maps are downloading fine so the issues seems to be the launcher won't/can't connect to Mojang's servers.

It's odd that I would get this exact problem the same day as this thread was posted. No previous problems, and not only with the newest launcher.

 

[twisto51]

I'm getting it too. Meanwhile the same account works just fine in ATLauncher.

 

[Dumle29]

Placing my PC in DMZ in my routher (no firewall) and dissabling windows firewall (I have no 3rd party firewall) doesn't help either[DOUBLEPOST=1387044333][/DOUBLEPOST]Here's my log:

[psyco59]

Had this for a few minutes but looks good now. Might of been a short server hiccup somewhere along the way

 

[DylanH]

I have the same problem, changed nothing, 2 hours ago everything worked fine. Login in the vanilla launcher works fine.[DOUBLEPOST=1387044469][/DOUBLEPOST]ok now it works again for me, really strange...

 

[Dumle29]

Even tho the .exe version has worked for me up to this point, it doesnn't any more. The Jar version however seems to work for me.

 

[Sidius]

I am having same problem too hope it gets fixed soon

 

[Aleck]

I was having this problem as well, I checked Mojang server status and everything appeared to be running fine. Took about 5-6 tries and maybe 10 minutes, but I eventually got it to work without changing anything or doing anything. Maybe some servers are flickering and experiencing issues?

 

[Bagman817]

Same here, was working fine an hour ago, now won't launch. Problem appears to be on the FTB side, can log into minecraft.exe fine. Also, clicking 'yes' to do you want to play offline just hangs the launcher. Looks to be specific to certain packs. This happens on DW20 1.6.4, but Unleashed launches normally.

This is something i did that solved my issue. Make sure your Java is up-to-date and correct. If using 64-bit, get BOTH java 7 update 45 (64-bit) and java (TM) 7 (64-bit). Delete any other Java updates or (TM) that are not 64-bit. Delete everything related to FTB. Horizon modpack, assets, libraries, etc.. then redownload the launcher and attempt to login again. This may ONLY work for 64 bit users. Hope this helps.

And now it randomly works again. Time to import to MultiMC =)
