Hi
My turn now.
I did some tests. Step by step:
1. I installed Acrylic, set all as it was wrote in your tip.
2. Restarted PC
3. Reinstalled meder to 4.0.4
4. I set meder ip and set meder DNS = my PC IP
- 1st problem - when i tried to set date to internet time meder hang for infinity time, only one way was unplug it.
- next time i tried again internet time - same problem
- next time i skipped internet time.
5. When i tried access from PC to meder it worked. I saw directories, i was able do everything. It looks like Acrylic (also your tip) success.
6. Next problem with this configuarion is that i can't use meder internet radio with PC off (often scenario at my home) cause meder DNS IP is my PC IP which is off

. Changing meder configuarion all the time is not solution for me.
7. It was working so i decided to revered situation.
8. I changed meder DNS address to router IP. Now i was able to set internet time and use internet radio with PC off. Access to meder from PC still worked. After each operation i restared both devices (meder na PC).
9. Next step - i set PC dns ips to provider as it was before. Restart PC. Access skill worked.
10. I stopped Acrylic. Restarted PC. Access still worked.
11. I uninstalled Acrylic. Restared PC. Access still worked. Of course i had an access from meder to PC also.
There is another strange thing. When i had DNS IP on my PC set to 127.0.0.1 (2nd one empty) and disabled Acrylic i still was able to use internet, WWW still works, email also. Its starane for me

So, it works now. I [CENSORED]ed up with one thing, before all those tests i should install 4.0.4 once again and test is it working or not with standard settings. But i didn't.
Conclusion. I dont have any

Maybe DNS is a reason but still im not sure that. Maybe something refreshed, maybe another instalation of 4.0.4 had any influence, maybe there is some random reason. Now i will leave it as it is, without Acrylic with standard settings. We will see, i will report any problem or idea connected to this copic.
Ty for your help.
