Disconnecting, but only in dungeons?

[x_zenith]

Typically it's right when I zone into a dungeon, this time it was right when I passed the purple threshold into the final boss' room.

I narrowed it down to dungeons, because I sometimes leave my character logged in for hours and hours at a time while AFK and never come back to a disconnect; it's specifically in dungeons. I tested it just yesterday and left my character logged in the entire day I was at work, and didn't D/C. Literally the second dungeon I did after getting home gave me a random D/C upon zoning in. It doesn't happen EVERY dungeon, but it does happen often enough to be worth posting in tech support forums

Any help or information would be appreciated!

If it helps, during the disconnects I don't actually lose connection to the internet. The browser works just fine, no packet loss, no error code in-game for it either.

EDIT: I'm not sure if this is relevant but it is a VERY RECENT issue. I recently reinstalled, made an alt and leveled it up a bit. I got it to 50+ and not one d/c upon dungeon entry. I switched back to my main and decided to purchase and install Stormblood and give it a try - this issue has ONLY happened so far in Stormblood dungeons, I don't know if it's restricted to those but it has only happened in those so far.

EDIT#2: Issue seems to have resolved. I changed from a static IP to a dynamic IP and did an IP /release and /renew, as well as a DNS flush.
