I found a solution that has somewhat worked for me...at least I am getting somewhere:
okay, since it's my first post, I can't put the link in here, so here is what I did below:
here is what I did, as mentioned in that link:
******FIX********
I tried many other acclaimed fixes, but to no avail. Ended up finding the solution myself. I had the issue on wifi but not data. My problem turned out to be my phones DNS settings. Go to settings then navigate to your home wifi network. Press and hold on your network, then modify network config. Then change your IP settings from dchp to static. Then you will need to scroll down to DNS 1 & 2. I changed mine to the public Google DNS services. The Dns server addresses are as follows:
8.8.8.8
&
8.8.4.4
Enter these and hit save. This did the trick for me! I also had issues with Google play updating and installing apps on my home net but worked fine elsewhere. This got rid of this issue as well. Note: these instructions are for the Galaxy S3. If you need help, just reply but try to use your on wits and think for yourself like I did. Just use my instructions as a guideline.
I'm glad I could help!
Good luck everyone!
BUT....this works for me for about 3-4 hours, then reverts back. I originally also had a problem downloading updates from the google play store...keeping these dns settings still has that problem fixed, but not the youtube issue.
I have gone to my kids school tonight for basketball--connecting to their wifi and youtube works, but here at home on my brand new 5g high-end netgear router it won't work!
So, to get youtube working again, I have to delete my wireless connections saved on my phone, reconnect, then manually edit and change the dns server to something besides my "normal" ones(which is comcast), then it works. I don't know how long it will continue to work tonight.
Also, what is strange is, I had already changed my DNS to point to Googles, but I still had to physically change it on my phone...only then did youtube start working again(or allow me to download app updates from google store).
Anyone have ideas here? it has to be something to do with the TCP/IP stack possibly on the phones being corrupted?
Also, this happens on all android phones I have at my house. This includes two Galaxy SII's and two brand new Samsung Note 2's...I think this all started possibly within the past week, as I had been watching videos fine on my note 2 since I bought it 6-8 weeks ago.
