Hi,

we have a few LOGO! 8 modules in the field.

When we try and access the web server on the devices, we are presented with a log on fail: 601 error.

At first we suspected that the NAT/PAT translation of the firewall was the cause.

From the internet, users will connect to their desired unit via a per-defined port. In this specific instance, the internet port is 8083 which the firewall then redirects internally to the LOGO ! internal IP address and port 8080.

We then tried internally directly to the Unit's IP address and port 8080, we are presented with a log on page, and type the password in. After a little while, we are presented with a Log on fail:601.

Does anyone know what an error 601 means?

Hi,

No, I mean that the Logos! is on a separate Sub Net to the central office network. Users on the central network get the error 601 intermittently.

Users connecting from the internet, will connect through the firewall address translation, they too get the error intermittently, however more often than those on the central network.

Initially I thought this was a routing issue, so I traced both;

user -> Logo! and

Logo! -> user

Both could route and follow the same gateway and router path.

I checked firewall logs for any application layer and port blocks, and there was nothing.

Also, I thought it may be latency on the line as some remote sites may not be on the best lines, however we average 96ms round trips with a data payload higher than the MTU, and there are no CRC errors or a high number of re transmits that we can pick up. (just no visibility on the Ethernet port of the Logo!).

Trouble is that this seems to affect some modules more than others.

Combined with this, we also get SSL Handshake Failed errors on the IOS App.

Basically, I am looking for more insight as to what is going on within the Logo! (logs etc) and better insight into the cause of the 601 from the WEB server 

Whas this problem solved?

I have the same problem from,time to time in Safari.

Deleting surf history and closing Safari solves the problem than.

now i Made a “webclip” (quick link to the web server on the main screen of ipad) to get faster acces and Some more the look and feel of An app. 

When I push this it connects to the login screen of the logo, but whe I log in than it imediately gives this “log in fail: 601”.

Anyone a idea how to solve this problem?

I have been trying Some things.

I always reach my Logo web browser through ddns:port and than log in On the page that I reach, and that always worked until now

but I also Made a favoriete in the safari browser, and than he took the adres of the page reached by going to “ddns:port” of wich he automaticaly made “ddns:port/logo_login.shtm?!App-Language=1”.

And when I go to this last one and try to log in he always gives the fault “log On fail:601”.

So I can make it work in the web browser, but I wantend to make a Apple webclip to get the more app look and feel (without the menu of the web browser On top).

when I make the webclip with ddns:port, it just opens Safari and I can log in normaly.

When i make the webclip with ddns:port/logo_login.shtm?!App-Language=1, it opens the “app look and feel” screen without the Safari menu On top and the complete screen filled with only the logo log in page. Here I can fill in my password than, but get the “log On fail:601”...

I hope this is explained a little understandable. 😎

maybe someone here can explain this?
