Raid bosses healing themselves?

Niantic wants to make those legendaries unbeatable.

From what I understand, it is lag between server and client. Same problem with the more commonly known "dodge bug".

I wonder if that has anything to do with this:

Oh, that's what happened when I (35) just tried to beat a Jolteon Thunderbolt along with a level 28 player. We did what we could do, but not even close

Oh great so 3s are no longer solosble

and now my watch has ended.

I was having that issue but I think it was lag. I have a hard time believing me, at level 38, couldn't solo an Electabuzz

Edit: Maybe I'm wrong...

I tried a magikarp, just to burn a free pass. Probably 2 wks ago. It took 8 se from my ttar and still timed out. Lag? Dodge bug? Who knows. About 1/2 the time that is the way it works for me. Yesterday I had an eggy boss beat with my scizor with 55 secs left, it wouldn't faint. I will not buy a pass that is for sure!

i can confirm, i lost two solo 3 raids because of this today. and burned through potions until I realized in the second raid that it was hopeless. no matter how many times i restarted, machamp and vape healed almost every charge move i hit. i normally beat machamp with 30 seconds left but because of glitch today i only got down it to a 3rd health. I also noticed that machamp healed itself when all my mons fainted and i rejoined the battle it had more health.
