It does look like a dns issue. Had to set wan and lan dns to googles then factory reset tv. Had a few issues but they seem to be slowly resolving themselves. One thing that could help is if you could setup a secondary dns on the tv and force dns cache clear. Netflix is now working more reliably but not 100%. Channel5 app does not stream anything at all. Bbc iplayer and play movies always work. I will monitor netflix for next few days. Thanks for the feedback.
I use netflix on webos tv with for profiles in netflix. Recently started to have issues with my netflix profile videos will not play they buffer slowly to 25% then nothing. Logged this with netflix who where helpful but baffled. The videos that dont play on my profile play perfectly on other profiles and perfectly on other devices on my profile. I have tried unistalling app resetting tv. Tried wifi and wired. Issues i can pinpoint point to combination of netflix on webos since update 4.0.9 updated to 4.1.0 same issue. Other thing i notice when video does not play the netflix network test shows internet connection is. Present but bandwidth of 0mbps. The tv itself using the speed 2 app shows between 40-80mbps. So it seems the app cant determine bandwidth or contact a streaming server. This is backed up as on my router it shows no attempt to contact a netflix ip when the videos do not play. So its not my internet but the app or tv or both not routing traffic or blocking it somehow. Why this only affects one profile in netflix and only on the webos tv i and netflix have no idea. They have said it must be a webis issue. Logged it by email to LG. Anyone else seen this? All other streaming apps work perfectly. Personally think something changed in webos update in january that altered routing or dns caching that the netflix app doesnt like. Any ideas comments welcome. Tv is lf652v
