Chrome Not Syncing After OS Upgrade

[doctormann]

Hi Guys

I have a bit of an odd situation. Here's the story:

I have a desktop machine (HP 1433-L) running Raphaella 64-bit and connected to my router with a CAT5 cable.

I have a laptop (Lenovo Z370) that was running Raphaella 32-bit, connected via wifi.

I use the Chrome browser on both and had no issues until I upgraded the laptop - new HDD, extra RAM, Raphaella 64-bit installed.

Now, for some reason, Chrome on the laptop will not sync to my Google account. The web store doesn't work either - can't add any extensions.

Chrome on the laptop says that syncing has failed. I get the 'oops!' message - tried following their suggestions to fix this but to no avail.

Apart from this, Chrome seems to work, as does everything else. I am mystified so I'm looking for suggestions.

Thanks,

DM

Looks as though this may be an MTU problem. I realised that the wifi connection on my desktop - normally use wired connection - wasn't working properly either and Pandora wasn't streaming. MTU was set to the default value of 1500 so I reduced it to 1488 - after doing the tests - and it now seems to work.

I still have to do this on my laptop. At the moment I have the old HDD with 32-bit Raphaella installed and MTU is set to 1488. I'll put the new HDD with the 64-bit Raphaella back in there at some stage, reduce the MTU to 1488 and see if this cures the sync problem on Chrome.

OK, can confirm that it was an MTU problem.

Everything working OK now.

Yep. The usual suspects are MTU packet fragmentation or DNS misconfiguration.

You may have a way of testing, but I'll leave this here anyway: www.letmecheck.it mtu-test

Thanks for that - could be handy so I'll bookmark it.

I've been testing from the command line - easy enough but a bit of a pain.
