I've only been at this for a couple of days and have been banging my head against the wall trying to upload to dtube. I kept getting the message "error while connecting to blockchain"
The answer was so simple I was kicking myself..
You can't use # in the tags... It's as simple as that
Write each word in the tag bar all in lower case and click somewhere off the tag bar so that word goes into its own little bubble then click back on and write the next word/tag
Hope that helps anyone having the same trouble I had
