What version of Ignition are you using? Would it be possible to get a Wireshark capture of Ignition connecting and browsing? ---

Can you upload the capture somewhere that I can access it? The pictures aren’t enough. ---

Sorry it doesn’t look like you actually captured the browsing. Only ReadRequest and ReadResponse appear in your captures. ---

sorry for my misunderstanding this time I first start the wireshark capture, then I use the designer to browse the TP700 tags, but there are no tags show in the ignition ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/c/ac604aa5bc244a9ef0a1e71c115180eeca5e94fa.png) also I try to click start then browse in the gateway ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/6/46c295914339065c480b6e2fb7bfb1a6aca68e47.png) the document you can see in the attachment[Browse in designer.zip](https://forum.inductiveautomation.com/uploads/short-url/8VnL5Rs8tEZkZkQSz2HPXGqu89I.zip) (64.7 KB) ---

Okay, on the settings for the OPC UA connection to this server in Ignition there should be an advanced setting called “Max Per Operation”. Try lowering this to 500 and see if you can browse the server after that. If not lower it again to 100 and try. ---
