感謝您的快速回饋。(一點背景資訊:我們每天都執行 S/R,也每天都執行 PTlive,只是通常不會在 VPN 啟用時進行)
您說得對,S/R 運作正常。我被這條訊息「搞混了」 
這條訊息會在啟動 PTlive 工作階段時出現。它只會出現一次。第二次嘗試啟動 PTlive 時,訊息不會出現,PTlive 也能正常啟動。
也許是逾時問題?
點擊「Start session」後,通常只需幾秒鐘即可啟動 PTlive,但在啟用 VPN 時,它似乎無法連線,並在約 120 秒後產生錯誤訊息。因此,對我來說這個問題是可以重現的。

Thanks for your quick feedback. (A bit of context : We do S / R every day and run PTlive every day as well, just not normally with VPN active)
You are right, S R works fine. I was "put on the wrong leg" by this message 
Which appears when a PTlive session is launched. It appears only once. The 2nd time one tries to launch PTlive, the message does not appear and PTlive is launched without a problem.
Maybe it is a timeout issues ?
Having clicked "Start session" this normally takes a few seconds to launch PTlive, but with VPN active it does not seem able to connect and produces the error message after about 120 seconds. So for me this problem is reproducible.
