I have gone through extensive port changes with my screenconnect install. During all this testing the port and URL of my screenconnect relay server has changed.

I created an easy vbscript to change the relay port and url on unattended machines.

You need to run this before changing your port/url. Then once all computers have been changed, change your SC server URL and port as desired.

Code:

'Change below to your custom values'
newrelayurl = "relayurl.com"
newrelayport = "443"

strComputer = "."  'could be any computer, not just the local one '
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

Set colServiceList = objWMIService.ExecQuery _
("Select * from Win32_Service where Name LIKE '%ScreenConnect Guest Service%'")
dim temp
dim OriginalImagePath
For Each objService in colServiceList
temp = objService.DisplayName
next

const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."

Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")

strKeyPath = "SYSTEM\CurrentControlSet\services\" & temp
strValueName = "ImagePath"
oReg.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue
OriginalImagePath = strValue
'Wscript.Echo OriginalImagePath
'Find Y
Dim MyArrayYFirst
Dim MyArrayYSecond
Dim y
Dim orig
MyArrayYFirst = Split(OriginalImagePath, "y=", -1, 1)
MyArrayYSecond = Split(MyArrayYFirst(1), "&", -1, 1)
orig = MyArrayYFirst(0)
y = MyArrayYSecond(0)
'Wscript.Echo y
'Find H
Dim MyArrayHFirst
Dim MyArrayHSecond
Dim h
MyArrayHFirst = Split(OriginalImagePath, "h=", -1, 1)
MyArrayHSecond = Split(MyArrayHFirst(1), "&", -1, 1)
If newrelayurl = "" Then
h = MyArrayHSecond(0)
Else
h = newrelayurl
End If
'Wscript.Echo h
'Find P
Dim MyArrayPFirst
Dim MyArrayPSecond
Dim p
MyArrayPFirst = Split(OriginalImagePath, "p=", -1, 1)
MyArrayPSecond = Split(MyArrayPFirst(1), "&", -1, 1)
If newrelayport = "" Then
p = MyArrayPSecond(0)
Else
p = newrelayport
End If
'Wscript.Echo p
'Find K
Dim MyArrayKFirst
Dim MyArrayKSecond
Dim k
MyArrayKFirst = Split(OriginalImagePath, "k=", -1, 1)
MyArrayKSecond = Split(MyArrayKFirst(1), "&", -1, 1)
k = MyArrayKSecond(0)
'Wscript.Echo k
'Find a
Dim MyArrayAFirst
Dim MyArrayASecond
Dim a
MyArrayAFirst = Split(OriginalImagePath, "a=", -1, 1)
MyArrayASecond = Split(MyArrayAFirst(1), "&", -1, 1)
a = MyArrayASecond(0)
'Wscript.Echo a
'Find T
Dim MyArrayTFirst
Dim MyArrayTSecond
Dim t
MyArrayTFirst = Split(OriginalImagePath, "t=", -1, 1)
MyArrayTSecond = Split(MyArrayTFirst(1), "&", -1, 1)
t = Replace(MyArrayTSecond(0), """","")
'Wscript.Echo t

newpathname = orig & "y=" & y & "&h=" & h & "&p=" & p & "&k=" & k & "&a=" & a & "&t=" & t & """"

strKeyPath = "SYSTEM\CurrentControlSet\services\" & temp
strValueName = "ImagePath"
strValue = newpathname
oReg.SetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue

For Each objService in colServiceList
objService.StopService()
WSCript.Sleep 15000
objService.StartService()
next
