I used an automatic translator for your question and based on the automatic translation, I understand that you have issues logging in to Virtual DataPort Administration Tool or Web Design Studio.
For your scenario, I would check the configurations below to log into Virtual DataPort Administration Tool or Web Design Studio:
* The Virtual DataPort server is running.
* Make sure you have entered the correct username/password. The default login username and password for Virtual DataPort Administration Tool and Web Design Studio is admin/admin.
* For the Virtual DataPort Administration Tool and Web Design Studio, the default connection URI is “//localhost:9999/admin”.
By following the above steps, I could log into the Virtual DataPort Administration Tool or Web Design Studio successfully. For more information, you can refer to [First steps - Launching Denodo](https://community.denodo.com/tutorials/browse/basics/2fs1controlcenter) section of Tutorials.
I would also check the **vdp.log** file located in “**<DENODO_HOME>/logs/vdp**” to know why the error is thrown.
If the above-mentioned suggestion is not working for you or your question is different, I would recommend you to post your question in English.
Hope this helps!!
