Hi. Some time ago I installed 6.0.688, later installed an 6.0.694 over it.
Found out that I wasn't supposed to do that - my bad.
Can I just upgrade to 6.0.750 now, or do I have to do a clean install?

You can try to install 6.0.750 manually

This update package is applicable to the TOS 6 beta version, but since you have installed 6.0.688 and upgraded to 6.0.694, it is recommended to reinstall 6.0.750.

Please define in subj that it is Beta version. Something like "TOS 6.0.750 (X86) is Released for Update (Beta)" should be enough so everybody will see what you'd like to release. Currently it is not clear enough from the first view. Thank you!

Version 6.0.750 is a stable release system. The second point in the note mentions that it is applicable for beta systems.

Been looking forward to this update to finally get the VPN working, actually for the first time ever got through the 'Create A VPN Connection' and onto the next stage, thought yes finally going to get this working then when clicked 'Connect' got the 'Operation Failed' message that I used to see previously, so still no VPN for me.

Hi everybody. In the first time, excuse me because my English is very bad. I´m from Spain.

I have a F2-424 and updated to version .750 and from that moment I can not reactivate the remote connection through TNAS.online or any other service like FTP, WebDAV or obviously connect with the mobile application. I set up the network manually and it doesn’t work either, and I don’t want to have to reinstall the system. Can the problem be solved in some other way? If you have to reinstall the system, is it necessary to extract all the information? I have about 2TB stored and I do not have another support right now to take out an external copy...

Attached an image with the error I get, something like that is not connected to Internet...



Thank you very much.
A greeting.

Hi, I remotely upgraded my F4-424 PRO to .750 and after a reboot I cannot reach it anymore. Unfortunately it's far from where I am now, I will check later the issue. In the meantime, do you have encountered any similar issues?

Regards.

F2-223 updated fine.

F4-223 after the post install, disk activity has started been going 1.5 hrs so far, still going.
Once it quiets down, I'll reboot it again. I think it's the Hyper Cache. If the disk activity starts up again, i'll wait until idle then delete the hyper cache, reboot then re-create the cache. Final test will be another reboot after all that. Since this only seems to happen after a release update, testing is limited. (If another post of mine shows up, sorry I thought I posted this earlier but don't see it)
