About a year ago my PS4's ability to use Share Play stopped working for no explained reason. I have tried almost every solution for this issue I could find on this forum and others, but have had zero luck. I bought a new modem, I forwarded ports, I bought new ethernet cables, no fix. I am going to try port triggering instead of port forwarding the next time I get a chance.
Any help would be greatly appreciated, this service used to work and I just want to get it back.
I am currently using an ASUS CM-16 Modem with a Nighthawk R6700v2 Router, before this modem I was using the Netgear CM500v. Both modems have given me the same results. I installed the ASUS Modem two days ago in the hopes that it would help with this issue.
I have tried connecting the PS4 directly to both modems and the result has been the same.
I found the Reddit post below with someone having the same problem that started around a year ago. My bet is on a PS4 update killed the UPnP client. Games still work because they have their own UPnP client programmed in. Sorry it doesn't help much but at least it shows you are not alone.
Do you have a friends PS4 you could borrow to try? One where Share Play has been verified working.
Thank you for the response WMO. I have an old PS4 I can set up again. I will also try some of the solutions offered in that reddit post you linked. I will report back here on the results.
