Openhab-Cloud: Unable to connect my openhab dashboard from

(Skinah) #21

I see it displays 1480 BYTES as working but in other area it states 1472 (1500) bytes… Maybe try setting your MTU to 1480 or a lower valve just for testing in your router and see if it solves your issue. If not just put it back to 1500.

Hi Skinah,

I have added following mtu size in /etc/network/interfaces, still I am observing same error
mtu 1472 – Getting same error
mtu 1500 – Getting same error.


Correct me, If I have added mtu size in wrong place.


(Dhanasekar Jaganathan) #23

After setting mtu value = 1472 in /etc/network/interfaces, It is not reflecting in network settings.

Hi Skinah,

After setting MTU to 1472, Still I am not able to access the dashboard and getting the same error,


(Dhanasekar Jaganathan) #25

I have observed that after setting mtu size to 1472 and then pinging ping -s 1472 -M do is throwing error.

Later I tried to decrease the mtu size and found mtu size 1443 is not throwing error. So I set that value to mtu size like this sudo ip link set enp1s0 mtu 1443.
After setting mtu size ,I tried to access OH’s dashboard but I am getting the same error ERR_CONTENT_DECODING_FAILED. Still I am unable access the dashboard.
When I ping with new set value ping -s 1443 -M do
, I am getting error.

It seems assigning what ever working value for mtu size, it is also not working after setting that value.

Hi Community & Skinah,

I have been waiting for guidance to fix this issue.
I have tried different network and different browser, still error is coming.
There may be no issues with firewall.

Please provide valuable inputs.

We didn’t do any changes on our end…
Can you ping the IP ( Any way to check with your provider if this is within a blocked range?

@Kai thanks for replying.
I check the ip

it is reachable.
check with my home service provider and they said, they didnt block the ip range or website…
and I can not reach the service from my cell phone data either.

the mainpage also doesn’t open

the only page that opens in with www
that leads to this:

when I click the login button at top, page doesn’t load

Hi Kai,

I have the same problem since some days. OpenHAB app doesn‘t connect anymore.

I can access

However I get an error

# 504 Gateway Time-out

nginx/1.10.3 (Ubuntu)

when trying to connect to

Any idea?

Many thanks

Same problem here! Any solutions? Or is myopenhab simply down?


(Dan Cunningham) #34

Our service is up, that error means either there is not an active connection to the service (or it thinks there is, but there is not). Can your try restarting the cloud bindle ? In the paper UI if you go to the cloud configuration screen and click save (with no changes), that should restart it ( i think)
