Last few days new difficulties connecting some sites but biggest problem example is “Google lens”. Messages include connection timed out and/or io.GRPC/14. Can I fix this, or anywhere to do so?

I am working oncan application which is to push records to azure table & blobs. My application ran for around 8 days perfectly fine but then it started giving connection time out error related to blob. Can anyone please guide to to workaround this?
Error logs below :

To resolve the error "java.net.ConnectException: Operation timed out (Connection timed out)" try below suggestions if helpful:
Try setting a small timeoutInterval and use a large maximumExecutionTime in your blobRequestOptions.
If the above does not work, use fiddler to verify that you are sending and receiving a response as expected.
Try checking the code you are using to upload files to Azure blob.
Check the system configuration and make sure there is no firewall that blocks the request from Java.
Connection timeouts usually occurs if there are too many requests overloading the server.
Otherwise, try uploading blob in chunk as a workaround.
If still the error persists, try using code snippet mentioned in this link.
Check whether the IP address/domain and port are incorrect or down.

Am working with wso2esb4.9.0 and having around 160 services which are http and are processed frequently, Initially when the server is started every thing is fine all service request response is up to the mark,
After 10-12 days the ESB server gets hanged does not process any request and no exception are seen in the log file even,They are some request which may be piled up in the server and not allowing new connection to process.
when i do restart of the server all the connections get releases and works for other 10-12 days again.
But doing a restart of the server may not be a good idea to do , where can i find these connections and close them if possible and am i missing any config changes of wso2 esb.
Am trying to find some different connection number using JMX and also what to know if any one face this issue and found the possible solution.
Basically this question asked multiple time but in my point, I can't able to clear out those so I want your side help for this error.
My app was complete with all decided features but it was giving me following error multiple time in log.
App is totally custom web server based and I was using GoDaddy server for placing admin panel content and for webservices.
In all loading pages , app has to call different web services. In this its work normally with good response but some time it will take so much time in loading page details and I got above kind of error log in XCode.
If next time, I call same service then its respond me quickly but some time, it creating problem for me.
From coding side, I am very much sure its just delay in server response because process become stuck in waiting of server response.
I'm getting started with websocket-rails, trying to convert an old polling system for notifications (on Ruby 2.1/Rails 4.0) to something a bit more modern with WS. I'm using WebsocketRails in standalone mode, here is my configuration, basically, the default:
WebsocketRails.setup do |config|
config.standalone = true
end
I have also setup a fresh Redis running on the default port - there seems to be no communication issues here.
On the client side, I have added the websocket-rails's JS and when trying to open an connection and subscribe to a channel, with:
#dispatcher = new WebSocketRails "localhost:3001/websocket"
#channel = #dispatcher.subscribe "notifications"
I see an error in the Chrome console:
WebSocket connection to 'ws://localhost:3001/websocket' failed: Invalid frame header
In Firefox, the error is different but still an error:
The connection to ws://localhost:3001/websocket was interrupted while the page was loading.
From the websocket server logs, I can see that a connection has been initiated and then dropped, but there are no other logs, even tho log level is "debug"... There are no other errors that I can see and a cursory Google search doesn't bring up anything regarding "invalid frame header", so I'm pretty much stuck.
Any help would be appreciated!
EDIT: I ended up using NodeJS+Faye to get things moving, and it has been working so well that I'm happy to introduce this new moving part in the system. I'm sure the issue was just something temporary based on my specific setup but sometimes, you just have to get things done.
I think you are looking for the following resources:
From the question thread: debugging websocket in google chrome
Chrome developer tools now have the ability to list WebSocket frames and also inspect the data if the frames are not binary.
Process:
Launch Chrome Developer tools
Load your page and initiate the WebSocket connections
Click the Network Tab.
Select the WebSocket connection from the list on the left (it will have status of "101 Switching Protocols".
Click the Frames sub-tab. Binary frames will show up with a length and time-stamp and indicate whether they are masked. Text frames will show also include the payload content.
Theres also this (somewhat old) blog article from 2012: Inspecting WebSocket Traffic with Chrome Developer Tools
I think that there's something wrong with the format of the data being sent over the wire.
Carefully look at the format of the message. Has it been properly stringified? Do your brackets and parens, {}, [], and () all match? Did your IDE insert an extra somewhere? Try validating a message with a linter or an online validator.
Inspect the message on both the sender and receiver sides. Make sure that everything is correct.
This may not be the answer to the author's original question but I want to add a possible solution to this Invalid Frame Header error.
From my small research, Invalid Frame Header can be generated on Websocket protocol when the server sends an empty response (message with 0 length). 0 length in TCP signals that connection has been closed and therefore any data transmission after the empty message fails.
This is the link that helped me to find this solution. I hope someone in the future will find this useful and save some time.
I am developing a service which reads messages from SQS, does some processing and posts the result to a different service.
When I initially developed this, the service was working perfectly fine, however after some days (about 5 days) I got this exception:
com.amazonaws.http.AmazonHttpClient: Unable to execute HTTP request: Connection to https://sqs.us-east-1.amazonaws.com refused { org.apache.http.conn.HttpHostConnectException: Connection to https://sqs.us-east-1.amazonaws.com refused

at com.amazonaws.services.sqs.AmazonSQSClient.getQueueAttributes(AmazonSQSClient.java:453)
I reactivated the service and it started working again. My question is has someone faced this issue? If so what is the best way to handle such exception?
Other interesting fact is the same exception happened on all the hosts of the service at nearly the same time. Can this be because of an SQS outage or are such transient connection failures expected?
