I am a WebService asmx in c# with two methods. I was published this service on external server on port 8088, for connect to this service in firewall i made port forwarding from xxx.xxx.xxx.xxx:80(router) to 192.168.20.12:8088. In browser can connect to this web service(xxx.xxx.xxx.xxx/Service1.asmx). Now I create a SmartDeviceProject and when add this web service on WebReference in this mode: xxx.xxx.xxx.xxx/Service1.asmx I obtain this error: Unable to downloal following files from: xxx.xxx.xxx.xxx:8088/Service1.asmx?wsdl and when add in this mode: xxx.xxx.xxx.xxx/Service1.asmx?wsdl service successfully add but in this case in code:
When I execute a project obtain this error: Could not establish connection to network I get this error and if remove in all code port 8088 from Url.
Does anyone know how I can resolve this problem?

After you create the proxy instance, set the Url property to the correct value, just like the constructor sets it to the wrong value:
If I’m not mistaken, in SmartDevice projects (i.e. PocketPC) this exception means that you don’t have access to a network.
If you are running this in the emulator, then you need to ensure that both the emulator and the emulated device are configured to connect to either the internet or your local network, depending on where the service is hosted.
I created a database using SQL developer list of 1000 entries and it created successfully. The connection also succeeded. But today while I’m trying to connect there is an error occurring:
I can surely say it is not connecting I tried it in Command prompt also in prompt it is mentioning as Protocol Adapter Error.
What is the problem here?
What is meant by Protocol Adapter Error how can i overcome it?
What is Network Adapter Error?

Please check the listener to see if it is down:-
If you dont find the output of the listener then you have to start it. To do that type start in the LSNRCTL> prompt.
If the Oracle clients have been installed with 11.1.2.3 the TNS_ADMIN will be point to user_projectsconfigdbclient In that folder there should be a tnsnames.ora, if the Oracle DB is on the same machine you may want to copy the contents of database tnsnames folder to the TNS_ADMIN folder or as suggested change the environment variable.

the answer for your question is some times the listener will be shut-down at this point it will not allow you to connect to the database, for example when the machine restarts. Solution is : Go to services check the Oracle_ora Db —> tns_listener is in running mode are not if not restart the services.
SQL Developer problem: The network adapter could not establish the connection
Open the file sqldeveloper.conf in wordpad or your favourite text editor. The file is placed in the installation directory, probably:
Add the following line at the bottom of the file and save:
I had a similar issue where I also continuously got the same error. I tried many things like changing the listener port number, turning off the firewall etc. Finally I was able to resolve the issue by changing listener.ora file. I changed the following line:
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
I also added an entry in the /etc/hosts file.

При запуске сервера возникает ошибка —
В консоли сервера:
Could not establish connection to Steam servers.
А у клиента при попытке входа —
В консоли :

You cannot connect to this CS:GO server because it is restricted to LAN connections only.
У меня подозрения на порты, хотя вроде все что нужно открыл.
У меня открыты:
UDP: 3478,4379,4380,27000-27100
TCP: 27000-27100
Возможно я забыл какие-то порты.
Или проблема совсем в другом.
