Oleg,
I had this exact same question. I worked on it for a long
time and did extensive research and could not find a
solution. Finally I decided to pay Microsoft Professional
Support a $99 incident fee to get the following answer
(yours free today only)
===========MPS Response==============================
In my test environment, I can reproduce the same error on
your side. The result is as below:
1. I configure WSS to use the NETBIOS name
(
http://servername) and it works fine when connecting in
PWA (Project Web Access).
2. I configure WSS to use the FQDN name
(
http://servername.domain.com) and it works fine when
connecting in PWA.
3. I configure WSS to use SSL with the NETBIOS name
(
https://servername) and the same error occurs when
connecting in PWA.
4. I configure WSS to use SSL with the FQDN name
(
https://servername.domain.com) and the same error occurs
when connecting in PWA.
5. I configure WSS to use SSL with the IP address
(
https://xxx.xxx.xxx.xxx) and it works fine when
connecting in PWA.
In the meantime, I performed further research on the SSL
configuration with WSS and it seems this issue occurs in
the following process.
1. When we click "Save Changes" in the "Manage Windows
SharePoint Service" page, PWA tries to validate this WSS
URL by looking up the URL in WSS.
2. WSS uses the IIS metabase to figure out the server
instance for the URL.
3. For SSL, the IIS metabase only contains IP and Port
information and there is no host-header information.
4. WSS cannot find the host-header information in SSL in
the IIS metabase and returns the error "The server
instance specified was not found"
5. PWA receives the error and popup the error message.
Currently, our product team is investigating this issue
for improvement. Although I cannot guarantee, most likely,
this issue will be resolved in the next service pack of
WSS. Your understanding and patience are greatly
appreciated.
I understand you are anxious to resolve this issue for an
extranet deployment. At this time, I suggest we connect
WSS using the IP address as a workaround. The steps are as
below:
1. In IIS manager, obtain a new certificate issued to the
IP address of the WSS web site.
2. Enable SSL on the WSS web site and assign the new
certificate to it.
3. In Project Web Access, enter https://<IP
address>:443/sites in the "Create a site under this
SharePoint URL:" box.
4. Save changes.
Please let me know if the information and suggestion above
help.
Due to the nature of this issue, I am glad to help you
refund on this incident. To do so, please confirm the
following information with me.

I did reconfigure WSS to use the IP address by selecting
the IP address in the virtual directory settings instead
of "all interfaces". I forced my IIS site to "Require
SSL". I purchased a certificate for my IP address. I can
now run both PWA and WSS through SSL.
